Reaction Steps

5 g (31.8 mmol) of N-methyloctanamide (1a) are added at 0° C. to a suspension of 1.4 g (35 mmol) of sodium hydride (60% in grease) in 60 mL of tetrahydrofuran. The reaction mixture is stirred for 30 minutes at room temperature and a solution of 8.9 g (35 mmol) of 3-bromobenzyl bromide in 15 mL of tetrahydrofuran is then added. The mixture is stirred for 16 hours at room temperature. The reaction is stopped by adding 100 mL of water and is then extracted with ethyl acetate. The organic phases are combined and dried over sodium sulfate. The solvents are evaporated off and the residue is then chromatographed on silica gel (75/25 heptane/ethyl acetate). 7.4 g of N-methyl-N-(3-bromobenzyl)octanamide are obtained. Yield=71%.
