NEW PYRROLIDINE DERIVATIVES

摘要

The new derivative of formula (I) is synthesized by condensation reaction of compounds of formula (II) and (III) with condensation agent in anhydrous base solvent at 40-100 deg.C. In the formulas, R1 and R2 is opt. saturated alkyl group or aryl group that carbon number is 2-20 and 1-17, respectively. R3 is hydrogen or opt. saturated alkyl group or aryl/its derivative that carbon number is 1-20. This is useful as anti-hypertension agent.
