Versuchsvorschrift

(2S,4R)-N-(4-Chloro-phenyl)-N-[1-(4-hydroxy-benzoyl)-2-methyl-1,2,3,4-tetrahydro-quinolin-4-yl]-acetamide (0.1 g, 0.23 mmol) was dissolved in DMF (5 mL) at room temperature. K2CO3 (0.317 g, 2.3 mmol) was added. 1-(3-Bromo-propyl)-pyrrolidine (0.177 g, 0.92 mmol) was added and the reaction was allowed to heat to 80° C. overnight. The reaction mixture was concentrated in vacuo. The residue was partitioned between ethyl acetate and water, then extracted three times with ethyl acetate, dried over MgSO4, filtered and concentrated down. The crude residue was purified by silica gel chromatography (10% methanol/90% dichloromethane) to afford the product (0.01 g, 8%).
