Versuchsvorschrift

A mixture of of 92.7 mg (0.15 mmol) of 2-[3-[2-[benzyloxycarbonyl-[4-(pyridin-3-yl)butyl]amino]ethyl]-2-(3,5-dimethylphenyl)-1H-indol-5-yl]-2-methylpropionic acid, 80.2 mg (0.6 mmol) of 7-azabicyclo[2.2.1]heptane hydrochloride, 83.2 mg (0.16 mmol) of PyBOP reagent, 0.107 mL (77.8 mg; 0.77 mmol) of triethylamine, and 0.75 mL of dry methylene chloride was stirred at room temperature in a stoppered flask for 48 hours. The solution was then partitioned between 10 mL of ethyl acetate and 10 mL of 0.5 N hydrochloric acid. The organic phase was washed with 10 mL of saturated aqueous sodium bicarbonate solution and then with 5 mL of saturated aqueous sodium chloride solution. The ethyl acetate phase was then dried (magnesium sulfate), filtered, and concentrated in vacuo at room temperature. The residue was purified by preparative TLC on 6 Analtech tapered silica gel plates (20×20 cm), which were developed in 95:5 CH2Cl2-MeOH. The product band from each plate was isolated, combined, and extracted with 95:5 CH2Cl2-MeOH. Concentration of the extracts in vacuo yielded 85.9 mg (82%) of a very pale yellow glass; virtually homogeneous by TLC in 95:5 CH2Cl2-MeOH. 506 MHz 1H NMR (CDCl3) was complex, owing to rotamers, but was consistent with the assigned structure. Mass spectrum (ESI): m/e=697.6 (M+H).
