Reaction Steps
To a chilled solution of 4-(4-(5-(4-fluorophenyl)-2-(methylsulfonyl)-1H-imidazole-4-carboxamido)phenoxy)-N-methylpicolinamide (200 mg, 0.39 mmol) and K2CO3 (119 mg, 0.86 mmol) in DMF (3.9 mL), was added methyl iodide (29 μL, 67 mg, 0.47 mmol). The reaction mixture was allowed to warm to room temperature and stirred overnight. TLC indicates completion of reaction with a single major product. Solvent was removed under reduced pressure and the crude material was dissolved in H2O (20 mL) and extracted with EtOAc (3×10 mL). The organic fractions were dried over Na2SO4 and concentrated. The crude material was purified by SiO2 chromatography (DCM/MeOH from 100% DCM to 94% DCM/6% MeOH, the desired product elutes in 97% DCM/3% MeOH) to yield a white solid (149 mg, 72% yield). 1HNMR (400 MHz, CDCl3): δ 8.88 (s, 1H), 8.33 (d, 1H, J=6.0 Hz), 7.97 (m, 1H), 7.66 (m, 3H), 7.50 (m, 1H), 7.43 (m, 2H), 7.22 (t, 2H, J=8.4 Hz), 7.03 (d, 2H, J=9.2 Hz), 3.79 (s, 3H), 3.50 (s, 3H), 2.98 (d, 3H, J=5.2 Hz). MS (ESI): m/z 524.0 [M+H]+
