Procedure

Method L—Step a To a mixture of (R)-1-[4-Chloro-3-(5-fluoro-1H-benzoimidazol-2-yl)-phenyl]-piperidine-3-carboxylic acid hydrochloride (obtained as described in general method 3,4, step e) (0.01 g, 0.27 mmol) in dcm (2 mL), HATU (0.10 g, 0.28 mmol), TEA (0.08 mL, 0.56 mmol) and 2-morpholinoethylamine (0.04 g, 0.33 mmol) were added. The reaction mixture was stirred at room temperature overnight, washed with ammonium chloride solution (2 mL), filtered through a phase separator and organic solvent was removed. The crude was then purified by SCX column and flash chromatography (eluent: gradient from cyclohexane:EtOAc/1:1 to 0:1 to EtOAc:NH3 in MeOH (2M)/10:1). A further purification by preparative HPLC was done to obtain 0.03 g of the title compound (29%).
