To a mixture of 3-[(tert-butoxycarbonyl)amino]-6-(2,6-difluorophenyl)-5-fluoropyridine-2-carboxylic acid (16.1 mg, 0.0437 mmol), tert-butyl [(3S,5R)-1-(5-amino-2,3-dihydrofuro[2,3-b]pyridin-4-yl)-5-methylpiperidin-3-yl]carbamate (14.0 mg, 0.0402 mmol) and HATU (53.1 mg, 0.140 mmol), DMF (1.0 mL) was added followed by DIPEA (70.1 μL, 0.402 mmol). The reaction mixture was stirred at room temperature for 2 h, and then concentrated under reduced pressure. To the resulting residue, DCM (2.0 mL) was added, followed by TFA (2.0 mL). The mixture was stirred at room temperature for 30 min., and then concentrated under reduced pressure. The resulting residue was purified using RP-HPLC (XBridge™ C18 column, eluting with a gradient of MeCN/water containing 0.1% NH4OH, at flow rate of 30 mL/min.) to afford the title compound as a white solid (5.9 mg, 29%). LCMS calc. for C25H26F3N6O2 (M+H)+: m/z=499.2. found 499.2.
