Reaction Steps

2-Butyl-1-[4-(2-carbomethoxybenzoyl)benzyl]-4-chloro-5-[(trifluoromethylsulfonamido)methyl]imidazole (150 mg, 0.26 mmol, 1 eq), 1.000 N NaOH (0.55 mL, 0.55 mmol, 2.1 eq), methanol (20 mL), and water (0.5 mL) were mixed and stirred for 5 hours at room temperature under N2. The solvent was removed in vacuo. Water (50 mL) was added and the pH was adjusted to 4 with 1 N HCl. Tan solids precipitated. These were collected and dried to yield 80 mg.
