실험 절차

To a solution of 4-hydroxy-4-pyrimidin-2-yl-cyclohexanone (59.8 mg, 0.31 mmol) and (1R,3S)-3-isopropyl-3-{[7-(trifluoromethyl)-3,4-dihydroisoquinolin-2(1H)-yl]carbonyl}cyclopentanamine (110 mg, 0.31 mmol) of Step C-2 of Example 1 in CH2Cl2(10 mL) was added sodium triacetoxyborohydride (131 mg, 0.62 mmol). After being stirred overnight, more sodium triacetoxyborohydride was added to bring the equivalents of the reducing agent to 5 equivalents. After stirring for another 5 hrs, the reaction was quenched with aqueous NaOH. The resulting solution was extracted with EtOAc three times. The combined extracts were dried over MgSO4 and concentrated. Purification by flash chromatography followed by HPLC gave two isomers. Isomer 1 and isomer 2: MS calculated for C29H37F3N4O2: (M+H)+531; found 531.1.
