Procedure: A suspension of 10-[(2-methyl-2′-trifluoromethyl-[1,1 l′-biphenyl]-4-yl)carbonyl]-10,11-dihydro-5H-pyrrolo[2,1-c][1,4]benzodiazepine-3-carboxylic acid of Example 1, Step F (0.50 g, 1.02 mmol) in dichloromethane (5 mL) containing a few drops of N,N-dimethylformamide was treated dropwise under nitrogen with oxalyl chloride (0.12 mL, 1.38 mmol). After gas evolution subsided, the reaction mixture was refluxed for an additional 15 minutes. The cooled solution was evaporated to dryness to give the crude acid chloride as a brown solid. The acid chloride was then dissolved in dichloromethane (5 mL) and slowly added to a solution of bis-(3-dimethylamino-propyl)-amine (0.90 mL, 4.04 mmol) and N,N-diisopropylethyl amine (1.1 mL, 6.31 mmol) in dichloromethane (5 mL). After stirring for 2 hours, the reaction was quenched with water. The organic layer was sequentially washed with 1 N hydrochloric acid, 1 N sodium hydroxide and brine, dried over anhydrous sodium sulfate, filtered and concentrated in vacuo to give a brown oil. Purification was achieved by preparative HPLC on a Primesphere S C18 column (0.21×15 cm) using a solvent gradient from 60:40:0.1 to 80:20:0.1 acetonitrile-water-trifluoroacetic acid. After removal of the acetonitrile in vacuo, the aqueous solution was basified with 2.5 N sodium hydroxide then extracted with dichloromethane. The combined organic layers were dried over anhydrous sodium sulfate, filtered and concentrated in vacuo to give the title compound (0.24 g) as a white foam, m.p. 55–64 ° C. the reaction mixture was refluxed for an additional 15 minutes The cooled solution was evaporated to dryness to give the crude acid chloride as a brown solid the reaction was quenched with water The organic layer was sequentially washed with 1 N hydrochloric acid, 1 N sodium hydroxide and brine dried over anhydrous sodium sulfate filtered concentrated in vacuo to give a brown oil Purification After removal of the acetonitrile in vacuo then extracted with dichloromethane The combined organic layers were dried over anhydrous sodium sulfate filtered concentrated in vacuo

Procedure: GB-A 1,157,637, GB-A 1,157,638 and GB-A 1,157,639 disclose the reaction of 2-methylglutarodinitrile with diethylamine in the presence of hydrogen and palladium on barium sulfate or preferably palladium on carbon to form 5-diethylamino-2-methylvaleronitrile. Despite the long reaction time and a diethylamine excess of 200 mol % no tetraethyl derivative was found, although the diethylamino group reacts not only with the nitrile groups in position 5 but also with that in position 1 (ratio 4 to 1). DE-A 3,935,641 describes the synthesis of a secondary amine over a palladium catalyst. The reaction of dimethylaminopropionitrile takes place in this case with itself under hydrogenating conditions to form bis(3-dimethylaminopropyl)amine. The formation of a tertiary amine is achieved only when a spinel is used as support material which is considerably expensive to produce, and the yield is not more than 58%. reacts not only with the nitrile groups in position 5
