실험 절차

A mixture of 3-amino-4-{(3S,5R)-3-[(tert-butoxycarbonyl)amino]-5-methylpiperidin-1-yl}-6,7-dihydro-5H-cyclopenta[b]pyridin-7-yl acetate (256 mg, 0.633 mmol), 6-[2,6-difluoro-4-(methoxymethyl)phenyl]-5-fluoropyridine-2-carboxylic acid (188 mg, 0.633 mmol), HATU (481 mg, 1.26 mmol) in DMF (1 mL) and DIPEA (0.330 mL, 1.90 mmol) was stirred at room temperature for 2 h. The reaction mixture was quenched with water and then extracted with EtOAc (2 times). The combined organic extracts were washed with brine, dried over Na2SO4, and concentrated under reduced pressure. The resulting residue was purified by column chromatography on silica gel using CombiFlash® apparatus eluting with EtOAc/hexanes (50-100%) to yield 4-{(3S,5R)-3-[(tert-butoxycarbonyl)amino]-5-methylpiperidin-1-yl}-3-[({6-[2,6-difluoro-4-(methoxymethyl)phenyl]-5-fluoropyridin-2-yl}carbonyl)amino]-6,7-dihydro-5H-cyclopenta[b]pyridin-7-yl acetate as an intermediate.
