Procedure

A benzene solution (14.5 ml) containing diethyl allyl(2-carboxyethyl)malonate (1.95 g, 7.2 mmol) and oxalyl chloride (2.3 g, 18.1 mmol) was stirred at 70° C. for 1 hour. After cooling to room temperature, the reaction liquid was freed of solvent by vacuum distillation. Thus there was obtained 1.92 g of 4,4-dicarboethoxy-6-heptenic acid chloride (yields: 91%). Characteristic Values of 4,4-dicarboethoxy-6-peptenic acid chloride
