Abstract
NEW MATERIAL:A 4-alkyl-2-pyridyl-1-phthalazone derivarive of formula I: (R1 and R2 are lower alkyl groups; R3 is straight or branched chain alkyl group; R4 is H or lower alkyl group; R5 is alkyl group).
EXAMPLE: 7-Ethoxycarbonyl-4,6,8-trimethyl-2-(2-pyridyl)-1-phthalazone.
USE: Drugs for arteriosclerosis, anti-thrombotics and anti-thromboxane agents, having anti-thromboxane and blood vessel smooth muscle relaxing actions, useful for preventing and treating thrombosis and arteriosclerosis.
PROCESS: One mole of a 3-hydroxy-3-alkylphthalide derivative of formula II is reacted with 1W5 moles of a pyridyl hydrozine derivative of formula III in a solvent, e.g. ethanol, under heating at 50W100°C to give the objective compound of formula I.
