Methanol → 2-(5-oxo-5H-dibenzo[a,d]cyclohepten-2-yl)propanal semicarbazone

Participants

Reaction Steps

To a solution of 0.288 g. of 2-(5-oxo-5H-dibenzo[a,d]cyclohepten-2 -yl)propanal in 3 ml. of methanol is added a solution of 0.111 g. of semicarbazide hydrochloride in 0.5 ml. of water, followed by 1 drop of pyridine. The mixture is refluxed briefly and then poured into water. The product is extracted with ethyl acetate and the extract washed, dried and evaporated to afford, upon crystallization from ethyl acetate/hexane, 2-(5-oxo-5H-dibenzo[a,d]-cyclohepten-2-yl)propanal semicarbazone.
