2-Cyano-3-(6-bromo-2,3-dimethoxyphenyl)-propionic acid → 3-(6-Bromo-2,3-dimethoxyphenyl)-propionitrile

Participants

Reaction Steps

A solution of 2-cyano-3-(6-bromo-2,3-dimethoxyphenyl)-propionic acid (39.25 g, 0.125 mole), and 80 mL N,N-dimethylacetamide was stirred at 160° for 1.25 hr. After cooling to room temperature, the solution was poured onto ice with stirring. The solid was filtered, washed with water, dried (in-vacuo) to yield 32.7 g white solid, (97%); M+ 269.
