Versuchsvorschrift
Acetic anhydride (100 ml.) is added dropwise to a suspension of 2,3-dichloro-4-phenylacetylanisole (29.5 g., 0.01 mole) in bis(dimethylamino)methane (100 ml.) under nitrogen with cooling to maintain the reaction mixture temperature below 60° C. The reaction mixture is stirred at 25° C. for 2 hours, and poured into ice water (1500 ml.) to precipitate 7.4 g. of 2,3-dichloro-4-(2-phenylacryloyl)-anisole which melts at 87°-89° C.
