Potassium Carbonate → 2,2-Diphenyl-2-[1-[2-(p-tolyl)ethyl]-3-piperidyl]acetamide

Participants

Reaction Steps

A mixture containing 3-(R,S)-(1-carbamoyl-1,1-diphenylmethyl)piperidine (0.26 g), 4-methylphenethyl bromide (0.2 g), anhydrous potassium carbonate (0.3 g) and acetonitrile (10 ml) was heated under reflux for 4.5 hours. The mixture was partitioned between dichloromethane (30 ml) and 10% aqueous sodium carbonate (30 ml), the layers separated, and the aqueous layer extracted with dichloromethane (2×30 ml). The combined dichloromethane extracts were dried (MgSO4) and concentrated in vacuo to give a colourless solid which was recrystallised from methanol to give the title compound, yield 0.13 g, m.p. 167°-169° C.
