반응 단계

To a suspension of cis-4-amino-N-isopropylcyclohexanecarboxamide hydrochloride (7.09 g, 32.1 mmol) and DIPEA (15 mL, 88 mmol) in ACN (50 mL) was added (3-fluoro-4-nitrophenyl)methanol (5 g, 29.2 mmol). The reaction was stirred overnight at 80° C. The reaction mixture was concentrated, loaded onto a silica-gel pre column, and purified by column chromatography, eluting with 0-100% EtOAc in DCM, to provide cis-4-(5-(hydroxymethyl)-2-nitrophenylamino)-N-isopropylcyclohexanecarboxamide as an orange foam (7.0 g, 71.4% yield). MS, m/z (C17H25N3O4): calcd, 335.2. found, 336.0 [M+H].
