Procedure

170 mg (1.0 mmol) N-[3-chlorophenyl]urea, 100 mg (0.77 mmol) 4-cyanobenzaldehyde and 100 mg (0.77 mmol) ethyl 3-oxobutanoate are suspended in 2 ml of THF, and catalytic amounts of concentrated hydrochloric acid are added. The mixture is stirred at reflux for 18 hours. After cooling down to room temperature, the solvent is removed in vacuo and the residue is purified by column chromatography on silica with cyclohexane/ethyl acetate as eluent.
