Versuchsvorschrift

2-(3-Ethylsulfanyl-phenoxy)-5-fluoro-nicotinic acid (150 mg, 0.51 mmol) was added to a solution of N-(4-amino-cyclohexyl)-3-hydroxy-2,2-dimethyl-propionamide hydrochloride (80:20 cis:trans, 135 mg, 0.54 mmol) and triethylamine (0.21 ml, 1.5 mmol) in dimethylformamide (3 ml) under nitrogen at room temperature. 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (108 mg, 0.56 mmol) followed by 1-hydroxybenzotriazole (76 mg, 0.56 mmol) were then added and the reaction was stirred at room temperature for 20 h. The mixture was concentrated under reduced pressure, partitioned between ethyl acetate (20 ml) and water (20 ml) and the organic phase was removed, dried over MgSO4 and concentrated under reduced pressure. The residue was purified by flash column chromatography on a silica gel eluting with a solvent gradient of dichloromethane:methanol (95:5) and the product was purified by preparative HPLC to give two products.
