Reaction Steps

A mixture of 7.0 g (0.015 mole) of trans-4-chlorobenzoic acid ester with 4-[(4-chlorobenzoyl)(n-butyl)amino]1-ethyl-3-pyrrolidinol, 0.9 g (0.016 mole) of potassium hydroxide, 15 ml of water and 60 ml of methanol was heated on a steam bath for 1 hr, then concentrated to approximately 10 ml volume under reduced pressure. The residue was partitioned between water and methylene chloride. The organic layer was separated, dried and concentrated under reduced pressure. The crystalline residue was recrystallized from isopropyl ether to give 4.3 g (89%) of white powder; m.p. 96.5°-98.0° C.
