Reaction Steps

To a stirred solution of 2-fluoro-5-((5-(6-methylpyridin-2-yl)-4-(quinolin-6-yl)-1H-imidazol-2-yl)methyl)phenol (Example 81) (100 mg, 0.244 mmol) in acetone (5 mL) were added methyl 3-chloropropanoate (32 uL, 0.366 mmol) and K2CO3 (67 mg, 0.488 mmol) and the mixture was stirred at 60° C. for 20 hours. The reaction mixture was cooled to room temperature, diluted with H2O (20 mL), and extracted with CH2Cl2 (5 mL, 3 times). The organic layer was dried over Na2SO4, filtered, and evaporated under reduced pressure. The residue was purified by MPLC on NH silica gel (MeOH:CH2Cl2=1:50 (v/v)) to afford the title compound (88.4 mg, 75%).
