Reaction Steps
A solution of methyl 3,4-dimethoxyphenylacetate (18.5 g, 0.088 mole) and 2-(3-methylphenyl) ethylamine was heated at 180° for 1 h. The crude amide was dissolved in 50 ml of methanol and precipitated as fine needles with 150 ml of hexane to give the title compound (20.4 g, 74%). The mother liquor deposited more material which was recrystallized from toluene (charcoal) to give an additional 4.7 g (17%) of amide. The total yield of N-(3,4-dimethoxyphenylacetyl)-2-(3-methylphenyl) ethylamine, mp 101-102°, was 91%.
