Benzoyl chloride, 3,4,5-trimethoxy- → 3,4,5-trimethoxy-N-methylbenzamide

Participants

Reaction Steps

Combine 3,4,5-trimethoxybenzoyl chloride) (2.9 g, 17.0 mmol) and tetrahydrofuran (170 mL) and cool to 0° C. Add diisopropylethylamine (5.92 mL, 34 mmol). Add methylamine hydrochloride (1.26 g, 18.7 mmol). Allow to stir for 1 hour and concentrate in vacuo. Chromatograph on silica gel eluting sequentially with 50% ethyl acetate/hexane to give N-methyl-3,4,5-trimethoxybenzamide: TLC Rf =0.45 (silica gel, 50% ethyl acetate/hexane).
