Reaction Steps

3.2 g (0.05 mole) of potassium cyanide dissolved in 50 ml of water is placed in a reaction vessel. The solution is heated to 60° C and a solution of 8.3 g (0.023 mole) of 6-bromomethyl-2-(p-chlorophenyl)chromone in 1600 ml of ethanol is added in four portions, one every 20 minutes. Once the addition is complete the mixture is refluxed for 3 hours, evaporated to dryness and dissolved in water. The solid is filtered off and recrystallised from alcohol.
