实验步骤: 4-(6-Cyano-3-pyridinyl)benzoic acid (D9) (0.35 g) was dissolved in dry DMF and treated with EDC (0.51 g) and a catalytic quantity of HOAT. The reaction mixture was stirred at rt for 5 min, followed by the addition of 1-(isopropyl)-hexahydro-1H-1,4-diazepine dihydrochloride (D2) (0.28 g) and N,N-diisopropylethylamine (1 ml), and allowed to stir at rt overnight. After evaporation of solvent the residue was partitioned between DCM (15 ml) and water (15 ml). The DCM layer was dried (magnesium sulfate) and concentrated to leave a crude residue which was purified by flash chromatography [silica gel, step gradient 0-15% MeOH (containing 10% 0.88 ammonia solution) in DCM]. Pure fractions were combined and concentrated to give the free base which was converted into the HCl salt in DCM (2 ml) with 1N ethereal HCl (1 ml). Evaporation of the solvents afforded the title compound (E15) (8 mg). 1H NMR δ (methanol-d4): 1.4 (6H, d, J=6.4 Hz), 2.16 (2H, bs), 3.47-4.2 (8H, m), 4.2-4.4 (1H, m), 7.68 (2H, d, J=8 Hz), 7.85 (2H, d, J=8 Hz), 7.98 (1H, d, J=8 Hz), 8.29 (1H, dd, J=8 Hz), 9.04 (1H, d, J=1.6 Hz).
