Method P—Step a To a vial with 1-[4-Chloro-3-(5-methoxy-1H-benzoimidazol-2-yl)-phenyl]-pyrrolidine-3-carboxylic acid hydrochloride (obtained as described in general method 3,4, step e) (0.10 g, 0.25 mmol), HATU (0.10 g, 0.26 mmol), TEA (0.07 mL, 0.53 mmol) and 1-methyl-piperazine (0.04 mL, 0.33 mmol), dichloromethane (2 mL) was added and the reaction mixture was heated at 35° C. overnight. Reaction was cooled to room temperature, saturated NaHCO3 solution (2 mL) was added with stirring, the organic layer recovered by filtration through phase separator, and the solvent removed under reduced pressure. The crude was purified by SCX, trituration from diethyl ether and finally by preparative HPLC to obtain 0.04 g of the title compound (34%).
