실험 절차

To a solution of (1R,3S)-3-isopropyl-3-{[7-(trifluoromethyl)-3,4-dihydroisoquinolin-2(1H)-yl]carbonyl}cyclopentanamine (113.0 mg, 0.3188 mmol) of Step C-2 of Example 1 in THF (1 mL) was added 4-hydroxy-4-(1,3-oxazol-2-yl)cyclohexanone (80.3 mg, 0.443 mmol) followed by triethylamine (0.5 mL, 3.6 mmol) and finally sodium triacetoxyborohydride (135 mg, 0.638 mmol). After being stirred overnight, the reaction was quenched by addition of NaOH solution. The resulting solution was extracted with methylene chloride. The extract was dried over MgSO4 and evaporated in vacuo. The residue was purified by flash chromatography eluting with EtOAc/1% NH4OH to give two isomers. Isomer 1: 73 mg. MS calculated for C28H36F3N3O3: (M+H)+520; found 520.1. Isomer 2: 56 mg. MS found 520.1.\
