Claims1
A process is provided for the preparation of p-formyl-N,N-dipolyoxyalkylenesubstitutedaniline which comprises:
- (a) forming a solution of dimethylformamide in an N,N-dipolyoxyalkylenesubstitutedaniline;
- (b) adding to said solution a condensing agent selected from phosphorus oxychloride, thionyl chloride, phosphorus trihalide, phosphorus pentahalide, and acyl acid chlorides in an amount sufficient to form p-formyl-N,N-dipolyoxyalkylenesubstitutedanilinediacetate from the corresponding N,N-dipolyoxyalkylenesubstitutedanilinediacetate;
- and
- (c) hydrolysing said p-formyl-diacetate to form said p-formyl-N,N-dipolyoxyalkylenesubstitutedaniline product.
