Reaction Steps

A mixture of 4-piperazinylbenzoic acid ethyl ester (1.03 g), 4′-propoxy-4-methylsulfonyloxy-1,1′-bicyclohexane (1.4 g), potassium carbonate (0.91 g) in N,N-dimethylformamide (10 ml) was stirred for 8 hours at 130° C. The reaction mixture was poured into water, and extracted with ethyl acetate. The organic layer was washed with brine and dried, and the solvent was evaporated under reduced pressure. The residue was chromatographed on a column of silica gel eluting with dichloromethane/methyl alcohol (200:1) to give 4-[4-(4′-propoxy-1,1′-bicyclohexan-4-yl)piperazin-1-yl]benzoic acid ethyl ester (0.26 g).
