실험 절차

To the m-phenoxybenzyl ester of N-phenyl valine (1.2 mmole) is added 12.5% phosgene in benzene (2.3 mmole), cooled in an ice bath, and then dimethylaminopyridine (1.22 mmole). The reaction mixture is stirred at RT for 3 days. Then one ml of benzene, 0.15 g of dimethylaminopyridine and 2 ml of phosgene are added and the reaction stirred overnight at RT. The reaction is worked up using chloroform/water. The chloroform layer is washed with dilute sulfuric acid, water and brine, dried over sodium sulfate and filtered. The solvent is removed by rotoevaporation to yield the m-phenoxybenzyl ester of N-chloroformyl,N-phenyl valine.
