실험 절차
To a solution of compound 4,4-difluorocyclohexanecarboxylic acid (3.5 g, 21 mmol) in 80 mL THF, 4-methylmorpholine (2.51 g, 21 mmol) was added at −70° C., followed by isobutyl chloridocarbonate (2.85 g, 21 mmol). 30 min later, 10 mL ammonium hydroxide was added. The resulting mixture was allowed to warm up to 0° C. After removal of all solvents, the residue was washed with water, PE to afford the compound 4,4-difluorocyclohexanecarboxamide (1.82 g, 40%) as a white solid.
