N,N-Diisopropylethylamine (63 μL, 0.36 mmol) was added to a mixture of 4-{3-(cyanomethyl)-3-[4-(1H-pyrrolo[2,3-b]pyridin-4-yl)-1H-pyrazol-1-yl]azetidin-1-yl}-3-fluorobenzoic acid (50.0 mg, 0.120 mmol), and benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (64 mg, 0.14 mmol) and 2-propanamine (11 mg, 0.18 mmol) in methylene chloride (10 mL). The reaction mixture was stirred at room temperature overnight. The reaction mixture was worked up with aqueous NaHCO3, and extracted with dichloromethylene (2×10 mL). The combined organic layers were washed with brine, dried over MgSO4, filtered and concentrated under reduced pressure. The residue was purified by RP-HPLC (pH=10) to afford the desired product. LCMS (M+H)+: m/z=458.1.
