To a solution of (5-Amino-pyridin-3-yl)-(7-isopropyl-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-methanone (Preparation 95, 50 mg, 0.17 mmol), (1-Cyclopropyl-3-trifluoromethyl-1H-pyrazol-4-yl)-acetic acid (Preparation 148, 47.1 mg, 0.21 mmol) and TEA (0.08 mL, 0.62 mmol) in THF (1 mL), 1-propylphosphonic acid cyclic anhydride (50% solution in EtOAc, 0.26 mL, 0.44 mmol) was added and the mixture was stirred at room temperature for 18 hours. The reaction mixture was evaporated under reduced pressure and the residue partitioned between water and EtOAc. The organic layer was washed with saturated sodium bicarbonate solution, dried (Na2SO4) and evaporated in vacuo. Purification by column chromatography on silica gel (EtOAc) gave the title compound as a white solid in 77% yield, 68 mg.
