Procedure

To a solution of (5-amino-pyridin-3-yl)-{1-[2-(tert-butyl-dimethyl-silanyloxy)-1,1-dimethyl-ethyl]-7-fluoro-1H-pyrrolo[3,2-c]pyridin-3-yl}-methanone (Preparation 29, 35 mg, 79 μmol), (3-trifluoromethyl-phenyl)-acetic acid (21.8 mg, 106 μmol) and DIPEA (48.94 μL, 277 μmol) in THF (3 mL), T3P (160 μL, 277 μmol) was added and the mixture stirred at 25° C. for 18 hours. The reaction was evaporated under reduced pressure, the residue partitioned between water and ethyl acetate, the organic extracts washed with saturated sodium bicarbonate solution, dried over sodium sulphate, evaporated in vacuo and triturated with pentane-ether to afford the title compound as a white solid (87%, 43 mg).
