Reaction Steps

Ethyl 2-(3-isocyanatophenylthio)propionate can be obtained in a manner analogous to that described in Example 1 for the preparation of tert-butyl (3-isocyanatophenylthio)acetate, but starting for 1 g of ethyl 2-(3-aminophenylthio)propionate, 0.54 cm3 of trichloromethyl chloroformate and 0.09 g of carbon. 1.18 g of ethyl 2-(3-isocyanatophenylthio)propionate are thus obtained in the form of an oil which is used as such in the subsequent syntheses.
