Reaktionsschritte

To a solution of cis-4-(5-(hydroxymethyl)-2-nitrophenylamino)-N-isopropylcyclohexanecarboxamide (3.75 g, 11.18 mmol) in DCM (127 mL) at 0° C. was added thionyl chloride (4.08 mL, 55.9 mmol) dropwise. The reaction was stirred at 0° C. for 3 hours and then at RT for 2 hours. The reaction was concentrated in vacuo and suspended in ACN and re-concentrated to remove residual thionyl chloride. The residue was resuspended in ACN (102 mL, 11.18 mmol), cooled to 0° C., and to it was added 2-(piperidin-4-yl)propan-2-ol (5.60 g, 39.1 mmol). The reaction was stirred at RT overnight. The mixture was filtered, and the filtrate concentrated in vacuo. The residual material was purified via silica gel chromatography, eluting with 90:10:1 DCM:MeOH:NH4OH to provide cis-4-(5-((4-(2-hydroxypropan-2-yl)piperidin-1-yl)methyl)-2-nitrophenylamino)-N-isopropylcyclohexanecarboxamide (4.64 g, 10.07 mmol, 90% yield) as an orange solid. MS m/z=461.4 [M+H], calc 460.61 for C25H40N4O4.
