反応手順

To a suspension of trans-4-aminocyclohexanecarboxylic acid (0.199 g, 1.392 mmol) and DIPEA (0.553 mL, 3.16 mmol) in ACN (5 mL) was added 2-(1-(3-fluoro-4-nitrobenzyl)piperidin-4-yl)propan-2-ol (0.375 g, 1.265 mmol). The reaction was stirred at 75° C. After 48 hours, the reaction mixture was concentrated, diluted with water (10 mL) and extracted with DCM and EtOAc. The combined organic layers were dried over anhydrous magnesium sulfate, filtered, and concentrated to provide trans-4-(5-((4-(2-hydroxypropan-2-yl)piperidin-1-yl)methyl)-2-nitrophenylamino)cyclohexanecarboxylic acid (0.524 g, 1.249 mmol, 99% yield) as an orange powder.
