反応手順
A mixture of 6-[(4-tert-butylphenyl)sulfonyl]-2-(trifluoromethyl)-6,11-dihydro-5H-pyrido[2,3-b][1,5]benzodiazepine-8-carbonitrile (intermediate 54, 26 mg, 0.0534 mmol), sodium azide (17.4 mg, 0.267 mmol), and ammonium chloride (14.3 mg, 0.267 mmol) in DMF (1 mL) was heated in a microwave reactor at 130° C. for 2 h. After cooling to room temperature, the reaction mixture was diluted with EtOAc, and organic layer was separated, washed with aqueous NaHCO3, water, brine, dried over MgSO4 and concentrated. The residue was purified via reverse phase HPLC to provide the title compound. LC/MS: m/e 530.0 (M+H)+. 1H NMR (500 MHz, CD3OD): δ 8.15 (1H, s), 7.88 (1H, d), 7.65 (1H, d), 7.10-7.20 (4H, m), 6.93 (2H, d), 4.60-5.00 (2H, br s), 1.25 (9H, s).
