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, 79.1 μmol), (4-trifluoromethyl-pyrazol-1-yl)-acetic acid (20.7 mg, 106.9 μmol) and DIPEA (48 μL, 276.8 μmol) in THF (3 mL), T3P (166 μL, 276.8 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 an off white solid (71%, 35 mg).
