To a solution of (1R,3S)-3-isopropyl-3-{[7-(trifluoromethyl)-3,4-dihydroisoquinolin-2(1H)-yl]carbonyl}cyclopentanamine TFA salt (40 mg, 0.1 mmol) of Step C-2 from Example 1 and 4-hydroxy-4-(5-methyl-1,3-thiazol-2-yl)cyclohexanone (32.6 mg, 0.15 mmol) in dichloromethane (10 mL) was added triethylamine (31 μL, 0.22 mmol) followed by sodium triacetoxyborohydride (56 mg, 0.26 mmol) at room temperature. After being stirred overnight, the mixture was diluted with methylene chloride and neutralized with NaHCO3. The organic layer was dried over Na2SO4 and concentrated. The residue was purified by flash chromatography on silica eluting with 5% MeOH/CH2Cl2 to give two isomers (13 mg and 10 mg). LC-MS calculated for C29H38F3N3O2S: (M+H)+550; found 550.2.
