Participants

Reaction Steps

Into a 25-mL round-bottom flask, was placed a solution of methyl 5-(4-cyano-2-(hydroxymethyl)-1H-imidazol-5-yl)-2,4-dimethylbenzoate (compound 219.6, 100 mg, 0.35 mmol) in methanol (10 mL) and a solution of NaOH (0.14 g, 3.5 mmol) in water (5 mL). The reaction mixture was stirred for 15 h at room temperature, then concentrated under reduced pressure. The pH of the solution was adjusted to 1-2 with hydrogen chloride (4 M). The resulting mixture 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 200 mg (crude) of the title compound as a light yellow solid.
