Industrial synthesis of N-(1'-allyl-2'-pyrrolidinyl)methyl-2-methoxy-4,5-azimido benzamide.

摘要

The invention concerns a novel process for the synthesis of N-[(1'-allyl-2'-pyrrolidinyl) methyl]-2-methoxy-4,5-azimidobenzamide, which successively comprises the preparation of 2-methoxy-4,5-diaminobenzoic acid, 2-methoxy-4,5-diacetylaminobenzoic acid, N-(2',5'-dihalopentyl)-2-methoxy-4,5-diacetylaminobenzamide, N-[(1'-allyl-2'-pyrrolidinyl) methyl]-2-methoxy-4,5-diacetylaminobenzamide and then N-[(1'-allyl-2'-pyrrolidinyl) methyl]-2-methoxy-4,5-azimido benzamide.
