実験手順

To a solution of (1R,3S)-3-isopropyl-3-{[5-(trifluoromethyl)-3′,6′-dihydro-3,4′-bipyridin-1′(2′H)-yl]carbonyl}cyclopentanamine (9.0 mg, 0.024 mmol), 3-methoxytetrahydro-4H-pyran-4-one (12.3 mg, 0.0709 mmol) and triethylamine (6.58 μL, 0.0472 mmol) in dry methylene chloride (2.0 mL) was added sodium triacetoxyborohydride (15.0 mg, 0.0708 mmol). After being stirred at room temperature overnight, the reaction was quenched with aqueous NaHCO3 and diluted with methylene chloride. The organic layer was separated and the aqueous layer was extracted with methylene chloride three times. The organic layers were combined, dried over MgSO4, filtered and evaporated under reduced pressure. The crude product (45 mg) was purified by silica gel column (30:70 MeOH/EtOAc) to provide 1.6 mg (14%) of pure product. LC-MS calculated for C26H36F3N3O3:(M+H) 496; found 496.1.
