实验步骤: 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%. The mixture is stirred for 16 hours at room temperature is then extracted with ethyl acetate dried over sodium sulfate The solvents are evaporated off the residue is then chromatographed on silica gel (75/25 heptane/ethyl acetate)

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 25 g (0.37 mol) of methylamine hydrochloride are dissolved in 125 mL of dichloromethane, and 115 mL of triethylamine are then added. At 0° C., 70 mL (0.41 mol) of octanoyl chloride are added slowly. The reaction mixture is stirred for 3 hours at room temperature. The mixture is filtered and 100 ml of water are then added to the filtrate. The organic phase is separated out by settling, dried over sodium sulfate and evaporated. 61 g of N-methyloctanamide are obtained in quantitative yield. The mixture is filtered 100 ml of water are then added to the filtrate The organic phase is separated out dried over sodium sulfate evaporated
