The crude product was purified by silica gel column chromatography to give the desired product as white soild. MS Calcd.: 314; MS Found: 315 (M+H)+, 337 (M+Na)+.
2.65 kg With N-ethyl-N,N-diisopropylamine; In isopropyl alcohol;Reflux; Large scale; 1.9kg crude previous step, 1.9kg2,4,5- trichloropyrimidine, 2.4kg diisopropylethyl amine 20kg of isopropanol was added, the reaction warmed to reflux.End of the reaction was monitored by HPLC, to the raw material 2-isopropyl-aniline sulfide content of less than 6%.Cooling to 40 ~ 55 dry reaction mixture was concentrated under reduced pressure, ethyl acetate was added 20kg entrained again.Ethyl acetate was added 20kg, 20kg purified water twice.Ethyl acetate phase was concentrated to dryness under reduced pressure, a dark oil was added to 10kg of anhydrous ethanol, 20 ~ 25 4 hours to crystallize with stirring, 0 ~ 5 crystallize with stirring and 16 hours.Filtered, 1kg ethanol washing once.40 powder dried in vacuo to give a white solid 2.65kg.
for 12h;Reflux; A solution of 2-aminothiophenol (125 g), acetonitrile (4 L), triethylamine (242.4 g) at 25 C was added bromoisopropane (123 g), and the mixture was refluxed at reflux for 6 hours. Cooling to room temperature, Dropping 2,4,5-trichloropyrimidine (180g), heated to reflux for 12h, The reaction is complete, cool down to 25 C, Add sodium phosphotungstic acid (4g), add 30% hydrogen peroxide (700ml), the temperature to 60 C, the reaction 2 hours, the reaction is completed, Add 10L of water, precipitation of solid, filtration, water and ethanol mixture (1/1) leaching, drying product 302g, purity 98.9%, yield: 87.2%.
