Versuchsvorschrift

5-Fluoro-2-(3-methylsulfanyl-phenoxy)-nicotinic acid (100 mg, 0.358 mmol) was dissolved in dimethylformamide (2 ml) and triethylamine (150 mg, 1.07 mmol) was added followed by cis-4-aminocyclohexanol hydrochloride (54 mg, 0.358 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (76 mg, 0.394 mmol) and 1-hydroxybenzotriazole (53 mg, 0.394 mmol). The reaction was stirred under nitrogen at room temperature for 18 h and the solvent was removed under reduced pressure. The residue was partitioned between sat. sodium bicarbonate solution (5 ml) and ethyl acetate (10 ml) and the aqueous phase was extracted with ethyl acetate (2×10 ml). The combined organic extracts were washed with water (2×3 ml), brine (3 ml), dried over MgSO4 and the solvent was removed under reduced pressure. The residue was purified by flash column chromatography on silica gel eluting with dichloromethane:methanol:concentrated aqueous ammonia (98:2:0.2, by volume) to give 5-fluoro-N-(cis-4-hydroxy-cyclohexyl)-2-(3-methylsulfanyl-phenoxy)-nicotinamide (110 mg) as a white foam.
