Participants

Reaction Steps

A mixture of 3,5-dihydroxyaniline (2.0 g), 2-ethoxy-1,1-bis(ethoxycarbonyl)ethene (3.0 g) and ethanol (10 ml) was left to stand at room temperature for 2 days. The resulting solid was filtered off, dissolved in dimethylsulphoxide (20 ml) and then treated with water (100 ml). The resulting solid was washed with water, to give 1,1-bis(ethoxycarbonyl)-2-(3,5-dihydroxyphenylamino)ethene (3.2 g), m.p. 190°-192° C.
