Phenyl chloroformate → HCID 86622299, compound

Participants

Reaction Steps

A solution of 2 g of 2-amino-1,3-benzothiazol-6-yl 2,6-dichlorobenzenesulfonate, 3.34 g of phenyl chloroformate, 1.79 g of sodium hydrogen carbonate in 40 cm3 of tetrahydrofuran and 4 cm3 of water is stirred for about 60 hours at a temperature in the region of 20° C. After concentrating the reaction mixture to dryness, the residue is taken up in 20 cm3 of water. The solid is filtered off by suction and washed with twice 5 cm3 of water, and then dried in an oven at 50° C. 2.5 g of 2-[(phenoxycarbonyl)amino]-1,3-benzothiazol-6-yl 2,6-dichlorobenzenesulfonate are thus obtained in the form of a brown solid, the characteristics of which are as follows:
