Reaction Steps

A solution of 1,3-dimethoxybenzene (89 ml, 0.064 mole) in dry tetrahydrofuran (480 ml) was added during 10 minutes to a stirred solution of n-butyl lithium in hexane (350 ml, 0.6 mole) under an atmosphere of nitrogen. The stirred mixture was heated under reflux for 90 minutes, then a solution of N-methyl succinimide (77 g, 0.68 mole) in dry tetrahydrofuran was added dropwise. The mixture was heated under reflux for an additional hour and then allowed to stand overnight. The supernatant was decanted and the residue was hydrolysed with 20% aqueous ammonium chloride solution (280 ml) and extracted with chloroform. The washed and dried extract was evaporated and the residue recrystallised from ethyl acetate to give N-methyl 3-(2,6-dimethoxybenzoyl)propionamide (15 g, 10%, m.p. 134°).
