Procedure

To a suspension of (1H-benzo[d]imidazol-2-yl)(4-(3-morpholinopyrazin-2-yloxy)-phenyl)methanone as prepared according to Scheme 3, (0.2 g, 0.5 mmol) in DMF (1 mL) was added cesium carbonate (0.2 g, 0.7 mmol) and iodomethane (0.04 mL, 0.6 mmol). The resulting mixture was stirred at RT overnight. LC/MS showed complete conversion. Compound crashed out in MeOH. Filtered the resulting orange solid and rinse with copious amounts of MeOH. Solids were dried by vacuum pump overnight to afford (1-methyl-1H-benzo[d]imidazol-2-yl)(4-(3-morpholinopyrazin-2-yloxy)phenyl)methanone. MS (ESI, pos. ion) m/z: 416.1. (M+1). IC50 (uM) ++++.
