Potassium Iodide → N-(4-(Methoxymethyl)-1-(2-phenylethyl)-4-piperidinyl)-N-phenylpropanamide

Participants

Reaction Steps

A mixture of 3.1 parts of 2-bromoethylbenzene, 4.1 parts of N-[4-(methoxymethyl)-4-piperidinyl]-N-phenylpropanamide, 0.1 parts of potassium iodide. 2.4 parts of sodium carbonate and 80 parts of 4-methyl-2-pentanone is stirred and refluxed for 48 hours. The reaction mixture is poured onto water and the whole is shaken thoroughly. The organic phase is separated, washed with water, dried, filtered and evaporated. The oily residue is purified by column-chromatography over silicagel using a mixture of trichloromethane and 5% of methanol as eluent. The pure fractions are collected and the eluent is evaporated. The oily residue solidifies on triturating in n-hexane. The product is filtered off and dried, yielding N-[4-(methoxymethyl)-1-(2-phenylethyl)-4-piperidinyl]-N-phenylpropanamide; mp. 85° C.
