Water → alpha-Hydroxy[2-(beta,beta,beta-trichloroethoxycarbonyl)aminothiazol-4-yl]acetonitrile

Participants

Reaction Steps

To a mixture of 1.0 g. of 2-(β,β,β-trichloroethoxycarbonyl)amino-4-formylthiazole, 0.87 g. of KH2PO4, 6 ml. of water and 4 ml. of dimethylformamide is added 0.33 g. of KCN at room temperature and the mixture is stirred for 30 minutes. The reaction mixture is extracted with ethyl acetate and ethyl acetate layer is washed with water and dried. Evaporation of ethyl acetate gives α-hydroxy[2-(β,β,β-trichloroethoxycarbonyl)aminothiazol-4-yl]acetonitrile 1.127 g.
