Procedure

The title compound was prepared by taking ethyl 3-methoxy-4-oxopiperidine-1-carboxylate (148 mg, 0.000737 mol) in Methylene chloride (3 mL, 0.04 mol) and adding (1S,4S)-4-isopropyl-4-({4-[4-(trifluoromethyl)pyridin-2-yl]piperazin-1-yl}carbonyl)cyclopent-2-en-1-amine (0.31 g, 0.00081 mol;), Triethylamine (0.8 mL, 0.006 mol;) and Sodium triacetoxyborohydride (0.312 g, 0.00147 mol). The reaction was stirred overnight. The reaction was quenched with (20 mL) NaOH and extracted with (3×10 mL) CH2Cl2. The organic layers were collected, dried over MgSO4 and concentrated in vacuo. The crude was taken on to the next step as-is (410 mg, 98%). MS calculated for C28H40F3N5O4: (M+H) 568; found 568.1.
