Versuchsvorschrift

N,N′-Carbonyldiimidazole (68 mg, 0.424 mmol) was added to a solution of 2-((1-(4-methoxy-2,6-dimethylphenylsulfonyl)piperidin-2-yl)methoxy)acetic acid (acid unit S24) (150 mg, 0.404 mmol) in methylene chloride (5 ml) and the mixture was stirred for 1 h at room temperature. A solution of 4-(thiophen-2-yl)piperidin-4-ol (73 mg, 0.404 mmol) in methylene chloride (2 ml) was subsequently added and the reaction mixture was stirred for 15 h at room temperature. Thereafter, saturated sodium bicarbonate solution (10 ml) was added to the reaction mixture and the aqueous phase was subsequently extracted with methylene chloride (2×10 ml). The combined organic phases were extracted with saturated sodium chloride solution (10 ml), dried with sodium sulfate and concentrated in vacuo. The crude product was purified by flash chromatography with ethyl acetate/hexane (20:1).
