Abstract

1472952 Preparing esters and amides FUJISAWA PHARMACEUTICAL CO Ltd 25 April 1974 [13 Aug 1973 4 March 1974] 39596/76 Divided out of 1472951 Heading C2C [Also in Division C3] A method of acylating a compound having a hydroxy, amino or imino group comprises reacting the compound with a compound having a carboxy group in the presence of a catalyst of formula where R 1 is an organic group and R 2 O is the residue of a N-hydroxy compound having a pKa value of not more than 6. Thus R 2 O may be the residue of (a) a nitrogen containing ring N-hydroxy compound, (b) an aliphatic or aromatic hydroxy compound, e.g. a residue of formula where R 3 and R 4 are each nitro, cyano, carbamoyl, or esterified carboxyl, (c) or a residue of formula where R 5 and R 6 are each hydrogen, acyl, aryl or arylazo.
