Participants

Reaction Steps

4,4-difluorocyclohexanecarboxylic acid (1.48 g) was dissolved in methylene chloride (20 mL), and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide (1.68 g), 1-hydroxybenzotriazole (1.21 g), and (2-phenylethyl)amine (1.2 mL) were sequentially added thereto, followed by stirring at room temperature for 18 hours. Then, saturated aqueous sodium bicarbonate was added to the reaction liquid which was then extracted with chloroform. The extract was washed with water and further saturated brine, and then dried over magnesium sulfate. The solvent was evaporated and the resulting residue was purified by silica gel column chromatography (hexane-EtOAc) to obtain 4,4-difluoro-N-(2-phenylethyl)cyclohexanecarboxamide (1.96 g).
