Procedure: A solution of trans-2-hydroxymethyl-1-cyclohexylamine hydrochloride (130 mg, 0.78 mmol) and triethylamine (300 μl) in dimethylformamide (5 ml) was added to a solution of 5-fluoro-2-(3-methylsulfanyl-phenoxy)-nicotinic acid (218 mg, 0.78 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (165 mg, 0.86 mmol) and 1-hydroxybenzotriazole (116 mg, 0.86 mmol) in dimethylformamide (4 ml) and the reaction was stirred under nitrogen at room temperature for 48 h. The reaction mixture was concentrated under reduced pressure, and the residue was partitioned between ethyl acetate (25 ml) and water (25 ml). The organic phase was removed and washed with sat. sodium bicarbonate solution (25 ml) followed by 1M citric acid (25 ml) and brine (25 ml).
