Methyl 4-methyl-3-(2-methyl-1H-imidazol-5-yl)benzoate (compound 7.1, 219 mg, 0.95 mmol) was dissolved in a mixture of methanol (20 mL) and aqueous sodium hydroxide (5 mL, 2M). The resulting solution was heated at 50° C. for 16 hrs, then the reaction was cooled to room temperature and the organic solvent was removed under reduced pressure. The resulting aqueous residue was acidified to pH 3-4 with aqeuous HCl (2 M). The resulting solids were collected and dried to yield 128 mg (62%) of the title compound as a white solid. m/z (ES−) 215 (M−H)−.
