To a solution of (1R,3S)-3-isopropyl-3-{[7-(trifluoromethyl)-3,4-dihydroisoquinolin-2(1H)-yl]carbonyl}cyclopentanamine TFA salt (30.0 mg, 0.0846 mmol) from Step C-2 of Example 1 and 4-hydroxy-4-(2-methyl-1,3-thiazol-5-yl)cyclohexanone (25.1 mg, 0.119 mmol) in dichloromethane (8 mL) was added triethylamine (0.0236 mL, 0.169 mmol) followed by sodium triacetoxyborohydride (42 mg, 0.20 mmol) at room temperature. After being stirred overnight, the mixture was quenched by addition of saturated NaHCO3. The resulting solution was extracted with CH2Cl2 three times. The combined extracts were washed with brine, dried over Na2SO4 and concentrated. The residue was purified by flash chromatography on silica gel eluting with 5% MeOH/CH2Cl2 to give two isomers (15 and 12 mg). LC-MS for both isomers: calculated for C29H38F3N3O2S (M+H)+550; found 550.2.
