Reaction Steps
A solution of 600.6 gm of N-(2,2-dimethoxyethyl)-3,4-dimethoxy-phenylacetamide in 3 liters of concentrated hydrochloric acid is mixed with 3 liters of glacial acetic acid. After standing for 17 hours at ambient temperature, the mixture is poured onto ice. The crystals precipitated are subjected to suction filtration, washed with water until neutral, and dried.
