Reaction Steps

A solution of 17.0 g. (118 mmoles) of trans-1-ethyl-4-methylamino-3-pyrrolidinol in 180 ml of methylene chloride was mixed with 15 g of powdered anhydrous potassium carbonate and cooled to -5°. The mixture was kept at or below 0° C. while a solution of 22.0 g (118 mmoles) of p-nitrobenzoyl chloride in 100 ml of methylene chloride was added dropwise. After the mixture was stirred at ambient temperature for 18 hr, it was poured into 100 ml of water. The organic layer was separated, dried, and concentrated. The residue was crystallized from benzene to give 30 g (87%) of white crytals; m.p. 104°-108° C.
