Abstract
NEW MATERIAL:A 4-formyl-1-phthalazone derivative I (R1 and R2 are lower alkyl; R3 is alkyl; R4 is H, halogen, alkyl or alkoxy; R5 is halogen, alkyl, alkoxy, alkoxycarbonyl or caboxyl).
EXAMPLE: 7-Ethoxycarbonyl-6,8-dimethyl-4-formyl-2-(p-chlorophenyl)-1-phthalazone.
USE: Remedies for arteriosclerosis, thrombosis and thrombokisan, and intermediates for the synthesis of 7-ethoxycarbonyl-6,8-dimethyl-4-(β,β-diacetylvinyl)-2-substituted phenyl-1-phthalazone and its derivatives.
PROCESS: A compound I is prepared by oxidizing a compound III (a new material) with an oxidizing agent, e.g. N-bromosuccinic imide, etc.. The new material III is prepared by reducing a reactive derivative of the corresponding 4-carboxylic acid compound with a boron hydride complex compound in a solvent.
