YieldReaction ConditionsOperation in experiment
In acetone; Example 4 can be prepared by suspending free base (53.5 mg) in acetone (2 mL) and then incorporating L-malic acid (22 mg). Solids dissolve into a clear solution. The white crystalline solids precipitate from the solution. Vacuum filter and air dry the solids. Dry the malate salt in vacuum oven (65 C.) overnight to provide the title compound. The conditions to obtain the X-Ray powder diffraction (XRD) of Example 4 are essentially the same as the conditions described in Example 2. Thus, a prepared sample of the title compound is characterized by an XRD pattern using CuKa radiation as having diffraction peaks (2-theta values) as described in Table 4 below. Specifically the pattern contains a peak at 5.39 in combination with one or more of the peaks selected from the group consisting of 10.33, 12.16, 15.57 and 20.08 with a tolerance for the diffraction angles of 0.2 degrees

75.8% To a solution of ethyl 5-[1-[(2S)-2-methoxypropyl]-3-methyl-2-oxo-imidazo[4,5-c]quinolin-8-yl]pyridine-3-carboxylate (32.0 g, 76.1 mmol) in tetrahydrofuran (320 mL), slowly add MeMgBr (1.4M in tetrahydrofuran/toluene, 221.4 g, 6.92*) solution under N2 protection with temperature below 0 C. Stir the mixture at -5~0 C. for one hour under N2 protection. Add NH4Cl solution (15%, 320 mL) slowly to quench the reaction while keeping the temperature below 25 C. Then add ethyl acetate (320 mL). Warm up the mixture to 25~30 C. and stir for half hour. After separation of two layers, back extract the aqueous layer with tetrahydrofuran (160 mL). Wash the combined organic with brine (192 mL). Add active charcoal (1.6 g) to the organic layer and stir at 65~75 C. for 4-5 hours. Filter the mixture with Kieselguhr Silica-Thiol (1.6 g). Stir the organic layer at 65~75 C. for 2-3 hours; the mixture is then filtered by Kieselguhr Silica-Thiol. The organic layer is removed under vacuum and the re-crystallized with ethyl acetate/tetrahydrofuran to give 8-[5-(1-hydroxy-1-methylethyl)pyridin-3-yl]-1-[(2S)-2-methoxypropyl]-3-methyl-1,3-dihydro-2H-imidazo[4,5-c]quinolin-2-one as a light yellow solid (22.34 g, 72.2%). To a three-necked flask add 8-[5-(1-hydroxy-1-methylethyl)pyridin-3-yl]-1-[(2S)-2-methoxypropyl]-3-methyl-1,3-dihydro-2H-imidazo[4,5-c]quinolin-2-one prepared as above in this Method 3 (50.0 g, 123 mmol) and tetrahydrofuran (1500 mL). Stir the mixture and heat it to 45-55 C. to form an absolute solution. Filter and concentrate the filtrate under vacuum below 45 C. to 2.0-3.0V and add ethyl acetate (500 mL), then concentrate under vacuum below 45 C. to 7~8V. Stir the slurry at 70~80 C. for 6-10 hours, then cool to 20~25 C. and filter. Add ethyl acetate (135-140 g) and ethanol (13.5-14.0 g) to the residue. Stir the slurry at 70~80 C. for 6-10 hours; then cool to 20~25 C. and filter. Concentrate under vacuum to give the title compound as pale yellow solid (37.9 g, 75.8%). 1H NMR (CDCl3, 400 MHz) delta 8.86 (d, 1H, J=2 Hz), 8.76 (d, 1H, J=2.4 Hz), 8.71 (s, 1H), 8.64 (d, 1H, J=1.6 Hz), 8.21 (t, 2H), 7.85 (d, 1H, J=6.8 Hz), 4.36 (q, 2H), 3.88 (m, 1H), 3.62 (s, 3H), 3.23 (s, 3H), 2.79 (s, 1H), 1.95 (s, 1H), 1.71 (d, 6H, J=0.8 Hz), 1.33 (d, 3H, J=6.4 Hz)

YieldReaction ConditionsOperation in experiment
In n-heptane; butan-1-ol; at 90℃; Example 5 can be prepared as by adding free base <strong>[1386874-06-1]8-[5-(1-hydroxy-1-methylethyl)pyridin-3-yl]-1-[(2S)-2-methoxypropyl]-3-methyl-1,3-dihydro-2H-imidazo[4,5-c]quinolin-2-one</strong> (60.2 mg) to 1-butanol (0.5 mL) and then add 21.9 mg fumaric acid. Add heptane (5*0.5 mL), which produces thick white slurry, and stir at 90 C./500 rpm. Vacuum filter and dry under nitrogen. Solids are lost during recovery from filtration, though sufficient for XRD. Additional crystalline fumarate salt is prepared by adding free base (101.0 mg) to 1-butanol (0.5 mL) and then add 34 mg fumaric acid. Add heptane (6*0.5 mL) and crystalline seeds of the fumarate salt from first preparation and stir the mixture at 90 C./500 rpm for 1 hour. Recover the solids by vacuum filtration and dry the solids under nitrogen. Further dry the solids in a vacuum oven (65 C.) overnight to provide the title compound. The conditions to obtain the X-Ray powder diffraction (XRD) of Example 5 are essentially the same as the conditions described in Example 2
