A mixture of 4-chloro-3-nitro-6,7-dihydro-5H-cyclopenta[b]pyridine (19.4 mg, 0.10 mmol), tert-butyl [(3S,5R)-5-methylpiperidin-3-yl]carbamate (22.0 mg, 0.10 mmol) and triethylamine (40.9 μL, 0.29 mmol) in isopropyl alcohol (0.224 mL) was stirred at 100° C. for 40 min. The reaction mixture was concentrated under vacuum and the residue was purified by silica gel column chromatography using CombiFlash® (0 to 50% EtOAc in hexanes) to give the sub-title compound as pale yellow powder (36.8 mg, 100%). LCMS calc. for C19H29N4O4 (M+H)+: m/z=377.1. Found: 377.1.
