Methyl iodide → N-methyl-N-(3-{2-[4-(2-methyl-5-quinolinyl)-1-piperazinyl]ethyl}phenyl)acetamide

Participants

Reaction Steps

A solution of N-(3-{2-[4-(2-methyl-5-quinolinyl)-1-piperazinyl]ethyl}phenyl)acetamide (50 mg) was dissolved in THF (2.5 mL) and sodium hydride (60% w/w oil dispersion, 0.005 g, 1 eq.) was added at 0° C. After 5 minutes iodomethane was added (5 uL, 1.0 eq.) and the mixture was warmed to room temperature. After 10 h the solution was partitioned between water (3 mL) and ethyl acetate (3×5 mL). The combined organic extracts were washed with brine, dried over sodium sulfate and concentrated under vacuum. The crude was purified by flash chromatography on silica gel, eluting with a gradient from dichloromethane to dichloromethane-methanol (98:2) affording the title compound in 61% yield (0.02 g).
