Participants

Reaction Steps

The preparation was the same as in example 1. But one equivalent of p-Phenetidine was used instead of p-Anisidine and one equivalent of diethyl ethoxymethylenemalonate was used instead of dimethyl methoxymethylenemalonate. Ethanol was replaced by hexane. 21 g of the title compound was obtained which is a white solid melting at 55-56° C., UV 329 nm (E=802).
