실험 절차

To a mixture of 6-(2,6-difluorophenyl)-5-fluoropyridine-2-carboxylic acid (13.7 mg, 0.0541 mmol), tert-butyl [(3S,5R)-1-(5-amino-2,3-dihydrofuro[2,3-b]pyridin-4-yl)-5-methylpiperidin-3-yl]carbamate (15.9 mg, 0.0456 mmol), and HATU (59.1 mg, 0.155 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 (8.5 mg, 38%). LCMS calc. for C25H25F3N5O2 (M+H)+: m/z=484.2. found 484.2.
