실험 절차
To the 2-methyl-1-{[2-methyl-3-(trifluoromethyl)phenyl]methyl}-6-(4-morpholinyl)-1H-benzimidazole-4-carboxylic acid (353.0 mg), methanol (14.0 mL) was added. The slurry was heated to 60 C. and tromethamine (3.0 M solution in water, 1.0 equivalent) was added in four aliquots over 15 minutes followed by the addition of crystalline seeds of crystalline tromethamine salt from batch 1. The slurry was stirred at 60 C for 3 hours, cooled (1 C/min) to 20 C, and stirred at 20 C for 8 hours. The solids were isolated by vacuum filtration, dried at 60 C under vacuum for 5 hours. The yield of the tromethamine salt was 401.5 mg (˜88.9% yield).
