96.9% at 12.9 - 19℃; for 4.91667 h; Example 5; N-(2,4-Difluorophenyl)-N'-(4-methoxy-3-(4'-bromo-I '-methyl-lH-pyrazol-5'- yl) phenyl)urea (8); Both portions of 5-(2' -methoxy-5' -aminophenyl)-4-bromo-l-methyl-IH-pyrazole (2) from the previous example were combined by dissolution in toluene (15 L) at 27.6° C, suction filtration of the resulting solution, and rotary evaporation of the filtrate at <50° C and 10 mm HgA to a constant weight of 1127.0 g. A solution of 7 (1102.0 g of the 1127.0 g evaporation residue) in toluene (11.02 L) was stirred and refluxed at atmospheric pressure through a Dean-Stark trap under nitrogen. to remove 0.8 mL of water. After the condensate had become completely clear with no further accumulation of water in the Dean-Stark trap, the toluene solution was cooled under nitrogen to 12.9° C. To the resulting solution stirred under nitrogen was added 2,4- difluorophenyl isocyanate (617.9 g) by addition funnel over 40 minutes at a rate sufficiently slow to enable the reaction mixture to be maintained at 12.9-19° C with reactor jacket cooling. Solid started to precipitate in the reaction mixture about half way through the addition. After the addition had been completed, the reaction slurry continued to be stirred at 16° C under nitrogen. Conversion of 7 to 8 was 90percent, 91.2percent, and 92.6percent five, 60, and. 120 minutes, respectively, after the addition had been completed. Three hours after the addition had been completed, a second portion of 2,4-difluorophenyl isocyanate (24.4 g) was added, and, after continued stirring of the reaction mixture at 16° C under nitrogen for an additional 30 minutes, conversion of 7 to 8 was 94percent. One hour after the second addition, a third portion of 2,4-difluorophenyl isocyanate (9.7 g) was added, and, after continued stirring of the reaction mixture at 16° C under nitrogen for an additional 15 minutes, conversion of 7 to 8 was 95percent. The reaction mixture was then stirred at 20° C under nitrogen for an'additional 14.75 hours, after which conversion of 7 to 8 was 100percent. The reaction mixture was suction filtered, and the filtered solid was washed with 2.6° C toluene (2 x 1100 mL) and dried at 100° C and pressures falling to 1 mm HgA to provide 8 (1654.9 g, 96.9 percent yield) of 98.2 percent purity by HPLC with ca. 0.9 mole percent desbromo 8 as the largest impurity.

99.94% at -5 - 70℃; for 11 h; Large scale To a solution of 3-(4-bromo-2-methyl-2H-methyl-3-yl)-4-methoxy-phenylamine (16.7 kg) in acetonitrile (78.6 kg) in a 200 L-glass jacketed reactor with overhead stirring and nitrogen blanket at an internal temperature of <−10° C. 2,4-difluorophenyl-isocyanate (9.68 kg) was controlled charged through a 1 micron line filter at a rate substantially slow enough to prevent co-precipitation of the starting material in the product. After continued stirring at <−10° C. for approximately 1 hour post completion of the 2,4-difluorophenyl-isocyanate addition, the conversion of starting material to product was substantially complete. The product slurry was filtered and washed with cold acetonitrlie (26.3 kg) at <−5° C. producing the acetonitrile solvate of the product. Full house vacuum (30 in Hg ) was applied to the bottom outlet filter/dryer while nitrogen flowed through from the top enhancing the removal of volatile solvents without application of heat. Samples were removed from the bulk material and LOD was determined using an IR-200 Moisture Analyzer Instrument (Denver Instrument Company). The time course is shown below:
92.9% at -10℃; for 1 h; Inert atmosphere To a solution of 3-(4-bromo-2-methyl-2H-methyl-3-yl)-4-methoxy-phenylamme (16.7 kg) in acetonitπle (78.6 kg) m a 200 L glass jacketed reactor with overhead stirring and nitrogen blanket at an internal temperature of < -10 0C 2,4-difluorophenyl-isocyanate (9.68 kg) was controlled charged through a 1 micron line filter at a rate substantially slow enough to prevent co-precipitation of the starting material in the product. After continued stirring at < -10 0C for approximately 1 hour post completion of the 2,4-difluorophenyl-isocyanate addition, the conversion of starting material to product was substantially complete. The product slurry was filtered and washed with cold acetonitπle (26.3 kg) at < -5 0C producing the acetomtπle solvate of the product. Full house vacuum (~30 in Hg ) was applied to the bottom outlet filter/dryer while nitrogen flowed through from the top enhancing the removal of volatile solvents without application of heat. Samples were removed from the bulk material and LOD was determined using an IR-200 Moisture Analyzer Instrument (Denver Instrument Company). The time course is shown below:Drying of the "wetcake" was maintained at ambient temperature under full house vacuum (-30 in Hg ) for about 19.5 h at which time the LOD was 7.28percent. At this point, the temperature was raised to 70 °C under full house vacuum (-30 in Hg ) for 11 hrs to afford l-[3-(4-bromo-2- methyl-2H-pyrazol-3-yl)-4-methoxy-phenyl]-3-(2,4-difluoro-phenyl)-urea (24.2 kg, 99.94percent ΗPLC purity, form I determined by PXRD, and 92.9percent yield).
