Reaktionsschritte

To a solution of cis-4-amino-N-isopropylcyclohexanecarboxamide hydrochloride (12.58 g, 57.0 mmol) and DIPEA (29.0 mL, 166 mmol) in ACN (104 mL) was added 2,4-dichloro-5-nitropyridine (10.00 g, 51.8 mmol). The resulting mixture was stirred at RT for 24 hours. The reaction mixture was diluted with water and washed with DCM (×2). The combined organic layers were washed with a minimal volume of brine, dried over sodium sulfate, filtered and concentrated in vacuo. After almost complete concentration of solvent, EtOAc was added, and the solid precipitate was collected yielding cis-4-(2-chloro-5-nitropyridin-4-ylamino)-N-isopropylcyclohexanecarboxamide as a yellow solid (12.97 g, 73.4% yield).
