Versuchsvorschrift

A mixture of 8-bromo-6-[(4-tert-butylphenyl)sulfonyl]-2-(trifluoromethyl)-6,11-dihydro-5H-pyrido[2,3-b][1,5]benzodiazepine (0.860 g, 1.60 mmol, intermediate 53), zinc cyanide (0.112 g, 0.96 mmol), Pd2(dba)3 (0.293 g, 0.320 mmol), and dppf (0.443 g, 0.80 mmol) in NMP (6.5 mL) under nitrogen was stirred at rt for 0.5 h and at 100° C. overnight. After cooling to rt, the reaction mixture was diluted with EtOAc and filtered. The filtrate was washed with water (3×), brine, dried (MgSO4), filtered and concentrated. The residue was purified by flash chromatography, eluting with mixtures of hexane and EtOAc, to provide the title compound. LC/MS: m/e 487.2 (M+H)+. NMR (500 MHz, CDCl3): δ 7.94 (1H, d, J=1.6 Hz), 7.66 (1H, d, J=7.5 Hz), 7.53 (1H, dd, J=8.4, 2.0 Hz), 7.19 (1H, d, J=7.3 Hz), 7.13 (2H, d, J=8.7 Hz), 7.04 (1H, s), 6.94 (2H, d, J=8.6 Hz), 6.83 (1H, d, J=8.5 Hz), 4.70-4.90 (2H, br), 1.26 (9H, s).
