Abstract

NEW MATERIAL:A 4-formyl-2-phenyl-1-phthalazone derivative of formula I: (R1 and R2 are lower alkyl groups; R3 is alkyl group).
EXAMPLE: 7-Ethoxycarbonyl-6,8-dimethyl-4-formyl-2-phenyl-1-phthalazone.
USE: Drugs for arteriosclerosis, anti-thrombotics, or thromboxane A2 antagonistic drugs. An intermediate for 7-ethoxycarbonyl-6,8-dimethyl-4-(β,β-diacetylvinyl)-2- phenyl-1-phthalazone and its derivatives (the same drugs as described above).
PROCESS: A compound of formula II is oxidized with chromic acid or its salt to give the objective compound of formula I.
