PROCESS FOR PREPARING CARBOSTYRIL DERIVATIVES

摘要

A process for manufacturing carbostyril derivatives(I) with blood platelet coagulation inhibitary and antiinflammatory activities is described. Carbostyril derivatives(I) are prepared by the reaction of carbostyril(II) with carboxy alkoxy carbostyril(III), or by the reaction of carboxy alkoxy carbostyril with activated carboxyl group(IV) with amine(V).
