Reaction Steps

Into a 25-mL round-bottom flask, was placed a solution of methyl 3-(4-chloro-2-cyano-1H-imidazol-5-yl)-4-methylbenzoate (compound 234.4, 130 mg, 0.47 mmol) in methanol (4 mL). Then a solution of LiOH (45.4 mg, 1.90 mmol) in water (2 mL) was added to the reaction. The reaction mixture was stirred overnight at 30° C., then was concentrated under reduced pressure. The pH of the solution was adjusted to 3 with hydrogen chloride (1M) and was concentrated under reduced pressure. Methanol (5 mL) was added to the residue. The salt was filtered off, and the filtrate was concentrated under reduced pressure to give 150 mg (crude) of the title compound as a white solid.
