Reaction Steps

To a mixture of triethylamine hydrochloride 27.5 g (0.20 mol) and 37% formalin 16.3 g (0.201 mol) was added dropwise β-phenylpropionaldehyde 25 g (0.183 mol) at 20° to 35° C. and the mixture was reacted at 110° to 115° C. for 4 hours. After the completion of the reaction, the reaction mixture was cooled to 20° C. and extracted with 100 ml of diethyl ether. The extract was dried over anhydrous sodium sulfate, the solvent was distilled off, and the residue was distilled to give 2-benzyl-2-propenal (bp10 : 99° to 101° C.) in a yield of 71%.
