Participants

Reaction Steps

Procedure DD: To a stirring solution of (S)-(+)-1-(2-pyrrolidinylmethyl)pyrrolidine (1.0 mmol) and n-methylmorpholine (1.0 mmol) in dichloromethane (0.10M), slowly add 4-Bromo-2-fluorobenzoic acid chloride (1.0 mmol) diluted in dichloromethane. Stir reaction at room temperature for one hour. After this time wash the reaction with saturated aqueous sodium bicarbonate while extracting with dichloromethane. Dry the organic layer with sodium sulfate, filter and concentrate in vacuo to give the title compound. MS (m/e): 355.1/357.1 (M+1)
