実験手順
To a solution of 1-(4-aminophenyl)-7,8-methylenedioxy-3,5-dihydro-2,3-benzodiazepin-4(4H)-one (118 mg, 0.400 mmol) in DMF (3 mL) was added NCS (51 mg, 0.38 mmol). The mixture was stirred at room temperature for 20 h, diluted with EtOAc (50 mL), washed with water and brine, dried over Na2SO4 and concentrated in vacuo. The residue was purified by chromatography (1:1 hexane/EtOAc) to afford the title compound as a tan solid (60 mg, 0.18 mmol, 45%), mp: 256°-258° C. 1H NMR (CDCl3) 8.50 (s, 1H), 7.54 (s, 1H), 7.32(d, J=8.3, 1H), 6.82 (s, 1H), 6.77 (d, J=8.3, 1H), 6.69 (s, 1H), 6.04 (s, 2H), 4.33 (s, 2H), 3.42 (s, 2H).
