Reaction Steps

To a mixture of 4-chloro-3-nitro-6,7-dihydro-5H-cyclopenta[b]pyridine (144.2 mg, 0.7260 mmol) and tert-butyl [(3S,5R)-5-(trifluoromethyl)piperidin-3-yl]carbamate (from MolBridge, 179.9 mg, 0.6706 mmol) was added 1-butanol (3.0 mL) followed by DIPEA (493.7 mg, 3.820 mmol). The mixture was stirred at 150° C. for 6 h. After cooling to room temperature, the reaction mixture was concentrated under reduced pressure. The residue was purified by chromatography on silica gel (0-50% EtOAc in hexanes) to afford the sub-title compound as a pale yellow solid (179.2 mg, 62%). LCMS calc. for C19H26F3N4O4 (M+H)+: m/z=431.2. found 431.2.
