Procedure

17.8 g of phosgene are introduced into 60 cm3 of benzene then a suspension of 7.1 g 4-nitrobenzyl hydroxyacetate (Izv. Akad. Nauk. SSSR. Khim 1964 (4) 685-692, Chem. Abst 61, 4469g) in 150 cm3 of benzene. The mixture is agitated for 2 hours at ambient temperature, brought to 7°/8° C. and 5.16 cm3 of diazabicycloundecene is added. After maintaining for one hour at this temperature, the mixture is decanted and the supernatant phase is partially concentrated under reduced pressure at 30°/35° C. until about 30 cm3 is obtained and the product is used as it is for the following stage.
