Participants

Reaction Steps

Add 3.78 ml (36.7 mmol) diethylamine dropwise to a mixture of 10 g (73.4 mmol) hydroxyacetophenone and 4.852 g (73.4 mmol) malononitrile in 24 ml DMF with cooling at RT. Stir the dark mixture for 2 h at RT and then add slowly to water (200 ml), with stirring and cooling. Continue stirring the precipitate for 30 min at approx. 10° C., filter with suction, suspend in water twice more, and filter with suction again. Dry the residue at high vacuum to constant weight. 10.99 g (81.2% of theor.) of the target compound is obtained as a yellowish-brown solid.
