Abstract

NEW MATERIAL:A compound of formula I: (R1 and R2 are lower alkyl groups; R3 is alkyl group; R4, R5 and R6 are lower alkoxy groups).
EXAMPLE: 7-Ethoxycarbonyl-6, 8-dimethyl-4-formyl-2-(3, 4, 5-trimethoxy-phenyl)- 1-phthalazone.
USE: Drugs for arteriosclerosis, antithrombotics, and antithrombaxanes, useful as an intermediate for the synthesis of 7-ethoxycarbonyl-6, 8-dimethyl-4-(β, β-diacetylvinyl)-2-substituted phenyl-1-phthalazone for the similar applications.
PROCESS: A compound of formula I is oxidized with an agent, e.g. a chromate, N- bromosuccinimide, or manganese dioxide, to give the objective compound of formula I. The use of a catalyst makes possible the air or electrolytic oxidation.
