USE: Useful as a preventing agent and a remedy for thrombosis having inhibitory action on blood platelet aggregation and antimicrobial action, and further as a synthetic intermediate for a compound of formula II which is useful as a preventing agent and a remedy for angina pectoris, arrhythmia and thrombosis and a hypotensive agent.
PROCESS: A compound of formula III (R1' is lower phenylalkyl; R2' is lower alkanoyl) is reacted with a compound of formula IV (X1 is halogen) in a suitable solvent at 100W150°C to give a compound of formula V, which is then reacted with a dehydrogenating agent to afford the compound of formulaI(R1 and R2 are not H).
