Procedure

Into a round-bottom flask, was placed a solution of methyl 3-(4-cyclopropyl-2-(methoxymethyl)-1H-imidazol-5-yl)-4-methylbenzoate (compound 4.8, 35 mg, 0.12 mmol) in methanol (5 mL), a solution of sodium hydroxide (9.6 mg, 0.24 mmol) in water (0.3 mL) was added to the reaction mixture. The resulting solution was stirred for 2 h at room temperature, then diluted with water (5 mL). Aqueous HCl (6 M) was carefully added to adjust the pH to 1-2 and the mixture was extracted with dichloromethane (4×10 mL). The combined organics were dried (Na2SO4), filtered, and concentrated under reduced pressure to yield the title compound as a yellow oil (30 mg, crude), which was used in the next step without further purification.
