Methyl 2-(2-fluoro-5-((5-(6-methylpyridin-2-yl)-4-(quinolin-6-yl)-1H-imidazol-2-yl)methyl)phenoxy)acetate (Example 93) (32.5 mg, 0.067 mmol) was treated with aqueous NH4OH (28-30%, 1 mL). The suspension was stirred at room temperature. After 2 hours, the reaction mixture was diluted with H2O (3 mL) and stirred for 30 min. The precipitate was filtered, washed with water, and dried under vacuum for overnight to afford the title compound (26.8 mg, 86%).
