Reaction Steps

To a suspension of 1-(4-cyclohexylphenyl)piperazine dihydrobromide (2.5 g) and potassium bicarbonate (2.125 g) in N,N-dimethylformamide (6 ml) was added methyl 4-(2-chloroethylphenyl) benzoate (1.22 g) and stirred for 24 hours at 120° C. The reaction mixture was added to a mixture of water and ethyl acetate. The organic layer was taken and dried over magnesium sulfate. The magnesium sulfate was filtered off, and the filtrate was evaporated under reduced pressure to give methyl 4-[2-[4-(4-cyclohexylphenyl)-piperazin-1-yl]ethyl]benzoate (1.247 g).
