Potassium Carbonate → HCID 19007307, compound

Participants

Reaction Steps

A mixture containing 3-(R,S)-(1-carbamoyl-1,1-diphenylmethyl)pyrrolidine (0.3 g--see Preparation 8), 3,4-dichlorophenethyl bromide (0.27 g--see Preparation 14), anhydrous potassium carbonate (0.4 g) and acetonltrile (10 ml) was heated under reflux for 4 hours. On cooling to room temperature, water (40 ml) was added and the resulting mixture extracted with dichloromethane (3×30 ml). The combined dichloromethane extracts were dried (MgSO4) and concentrated in vacuo to give a foam which was purified by column chromatography on silica eluting with dichloromethane containing methanol (0% up to 7%). The product-containing fractions were combined and concentrated in vacuo to give the title compound as a colourless foam, yield, 0.22 g.
