Summary: | 1. A process for the preparation of N-formyl-alpha-aminoacid esters of the formula (V) see diagramm : EP0080119,P9,F1 where n is 0 or 1 and R**1 is hydrogen or, if n is 1, may also be alkyl of up to 4 carbon atoms, methoxy or methylthiomethylene, and R**2 is alkyl of up to 5 carbon atoms, wherein an aminonitrile of formula (I) see diagramm : EP0080119,P9,F2 where R**1 and n have the above meanings, is reacted with a corresponding alcohol in the presence of hydrogen chloride and of at least the amount of water which arises on formation of the aminonitrile from its cyanohydrin, and the reaction product is reacted with excess formamide at up to 160 degrees C. |
