Procedure

2-(5-Fluoropyridin-2-yl)acetic acid (23.1 mg, 0.149 mmol) (see Preparation 92) was added to (5-aminopyridin-3-yl)(7-tert-butyl-7H-pyrrolo[2,3-d]pyrimidin-5-yl)methanone (40 mg, 0.135 mmol) (see Preparation 31), 1-propylphosphonic acid cyclic anhydride (0.2 mL, 0.338 mmol, 50% in EtOAc) and triethylamine (0.65 mL, 0.474 mmol) in THF (3 mL). The mixture was stirred at 25° C. for 18 hours, evaporated in vacuo and partitioned between saturated aqueous sodium bicarbonate (5 mL) and ethyl acetate (5 mL). The organic phase was dried over sodium sulfate, evaporated in vacuo and the residue was triturated with pentane:diethyl ether (3:1, 1 mL) to afford the title compound as an off white solid in 65% yield, 38 mg.
