Procedure
65 g of POCl3 is added dropwise at 50° and while stirring to a solution, in 500 ml of DMF, of 31.3 g of p-carbamoylbenzyl p-ethoxyphenylacetate (obtainable by esterification). After stirring for a further hour, the mixture is poured onto ice and worked up in a customary manner to give p-cyanobenzyl p-ethoxyphenylacetate, m.p. 59°, c.p. -40°.
