Versuchsvorschrift

To a solution of 10-(2-methyl-2′-trifluoromethyl-biphenyl-4-carbonyl)-10,11-dihydro-5H-pyrrolo[2,1-c][1,4]benzodiazepine-3-carboxylic acid of Step F (0.50 g, 1.02 mmol), 1-(4-pyridinyl)-piperazine (0.20 g, 1.23 mmol) and 1-hydroxybenzotriazole monohydrate (0.15 g, 1.11 mmol) in N,N-dimethylformamide (4 mL) was added 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (0.22 g, 1.15 mmol) followed by N,N-diisopropylethyl amine (0.27 mL, 1.55 mmol). The reaction mixture was stirred overnight, diluted with ethyl acetate and washed with water and saturated aqueous sodium bicarbonate. The organic phase was then dried over anhydrous sodium sulfate, filtered and concentrated in vacuo to give a yellow oil. Purification by flash chromatography using a solvent system of 10% methanol in chloroform provided 0.39 g of the title product which was dissolved in dichloromethane and concentrated in vacuo to a white foam.
