Procedure
13.5 ml (105.6 mmol) of phenyl chloroformate are added, dropwise, at ambient temperature to a solution of 10 g (96.15 mmol) of ethyl glycolate and 27 ml (192.3 mmol) of triethylamine in 20 ml of toluene and the mixture is stirred at ambient temperature for 2 h. The salt formed is separated and the filtrate is concentrated under reduced pressure to obtain 20 g of oily product, which are used without modification in the following step.
