The procedure described in Example 28 is repeated, except that 8.23 g (0.05 mol) of 4-formylbenzoyl chloride and 6.25 g (0.0625 mol) of ethyl acrylate are used. After a reaction time of 13 hours at 120° C., 4.7 g (0.023 mol) of ethyl 4-formylcinnamate are obtained, corresponding to a yield of 46% of theory; boiling point 137°-140° C./13 Pa.
