Procedure

N-(cis-4-Amino-cyclohexyl)-5-fluoro-2-(3-methylsulfanyl-phenoxy)-nicotinamide hydrochloride (150 mg, 0.364 mmol) was dissolved in dimethylformamide (3 ml) and triethylamine (153 μl, 1.1 mmol) was added followed by 3-tetrahydrofuran-carbocylic acid (47 mg, 0.40 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (77 mg, 0.40 mmol) and 1-hydroxybenzotriazole (54 mg, 0.40 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 (3×10 ml). The combined organic extracts were washed with water (2×5 ml), brine (5 ml), dried over MgSO4 and the solvent was removed under reduced pressure. The residue was triturated with diethylether (5 ml) to give 5-fluoro-2-(3-methylsulfanyl-phenoxy)-N-{cis-4-[(tetrahydro-furan-3-carbonyl)-amino]-cyclohexyl}-nicotinamide (140 mg) as a white solid.
