실험 절차

A mixture of 30 g of 6,7-dimethoxy 3H-isobenzofuranone, prepared according to the method described in Example IV, 1 liter of ethanol and 300-400 cm3 of dimethylamine was agitated for several hours and then evaporated under vacuum at 30° - 35° C. The crystallized product was washed with heptane. The 2,3-dimethoxy N,N-dimethyl 6-hydroxymethyl benzamide was obtained in a yield of 100%. F = 90° C.
