Reaction Conditions

Reaction Steps

To a stirred solution of N-cyclohexyl-N-methyl 4-(1H-benzimidazylmethyl)benzamide (347 mg, 1 mmol) in dry THF (20 ml) at -78 ° C. was added sodium bis(trimethylsilyl)amide (1.1 ml of 1M solution in THF) under argon. The mixture was left to stir at -78° C. for 40 minutes, a solution of methyl iodide (170 mg, 1.2 mmol) in dry THF (2 ml) was added and the mixture left to warm to ambient temperature overnight. The reaction mixture was partitioned between ethyl acetate and brine, the organic layer dried (Na2SO4), concentrated to give a crude product which was purified by column chromatography (flash silica gel, 4% methanol in DCM) to yield N-cyclohexyl-N-methyl 4-(1-(1H-benzimidazyl)ethyl)benzamide (40 mg, 11%) as a white crystalline solid.
