実験手順
A mixture of 3-amino-4-((3R,4R,5S)-3-[(tert-butoxycarbonyl)amino]-4-{[tert-butyl(dimethyl)silyl]oxy}-5-methylpiperidin-1-yl)-6,7-dihydro-5H-cyclopenta[b]pyridin-7-yl acetate (324 mg, 0.606 mmol), 6-[2,6-difluoro-4-(methoxymethyl)phenyl]-5-fluoropyridine-2-carboxylic acid (180 mg, 0.606 mmol) and HATU (0.460 g, 1.21 mmol) in DMF (3.0 mL) and DIPEA (0.316 mL, 1.82 mmol) was stirred at room temperature for 2 h. After quenching the reaction with water, the mixture was extracted with EtOAc (2 times). The combined organic extracts were washed with brine, dried over Na2SO4, and concentrated under reduced pressure. The residue was purified by purified by column chromatography on silica gel using CombiFlash® apparatus eluting with EtOAc/hexanes (50-100%) to give an amide intermediate, 4-((3R,4R,5S)-3-[(tert-butoxycarbonyl)amino]-4-{[tert-butyl(dimethyl)silyl]oxy}-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.
