Process for the preparation of glycoloylanilides

摘要

A process for the preparation of glycoloylanilide of the formula (G) <IMAGE> (G) is recited that involves reacting a nitrobenzene with hydrogen and, if desired, with a carbonyl compound, in the presence of a noble metal catalyst and a solvent, reacting the compound produced with chloroacetyl chloride, reacting the resulting product with a benzyl alcohol and with a base, or reacting the resulting compound with an O-benzylglycoloyl chloride, and debenzylating the resulting benzylglycoloylanilide product by reacting with hydrogen in the presence of a noble metal catalyst. The invention also relates to a process for the preparation of O-benzylglycoloylanilide.
