Procedure

9.85 g of 1-naphthaldehyde were reacted with 15.2 g of 4-chloroacetoacetic acid ethyl ester in the course of 10 hours as described in Example 24. After incipient distillation under a high vacuum had been carried out, a 2:1 isomer mixture which still contained traces of aldehyde remained as the residue.
