実験手順

Method M—Step a To a mixture of (R)-1-[3-(1-methyl-1H-benzoimidazol-2-yl)-phenyl]-piperidine-3-carboxylic acid hydrochloride (obtained as described in general method 1, step d) (0.01 g, 0.30 mmol) (obtained as described in method A, step d) in dcm (2.5 mL), HATU (0.12 g, 0.33 mmol), TEA (0.09 mL, 0.63 mmol) and 4-methoxypiperidine (0.04 g, 0.33 mmol) were added. The reaction mixture was heated at 35° C. overnight, cooled to room temperature, washed with ammonium chloride solution (3 mL), filtered through a phase separator and organic solvent was removed. The crude was then purified by SCX column (eluent: first dcm:MeOH/1:1 then NH3 in MeOH (2N)) and flash chromatography (eluent: gradient from EtOAc:cyclohexane/10:0 to 0:10) to obtain 0.05 g of the title compound (38%).
