A mixture of 2-[1-(5-bromothiazole-2-yl)-4-pyrrolidine-1-ylpiperidine-4-yl]ethanol (1.30 g), (3-chloro-5-hydroxy phenyl)acetic acid (796 mg), tri-n-butylphosphine (0.99 mL), 1,1′-(azodicarbonyl)dipiperidine (1.00 g) and tetrahydrofuran (20 mL) was stirred at room temperature for 4 hours. To the reaction solution was added water and extracted with ethyl acetate. The organic layer was washed with water and brine, and dried over magnesium sulphate. The solvent was evaporated under reduced pressure and the residue was purified by column chromatograph on silica gel to give the title compound (1.45 g). Yield: 74%.
