Procedure
A stirred solution of 187 (120 mg, 0.39 mmol) in dry DMF (1.5 mL) was treated at 0° C. with N,N-dimethyl-1,2-ethanediamine (107 μL, 0.97 mmol), followed by the dropwise addition of diethyl cyanophosphonate (128 μL, 93%, 0.78 mmol). The mixture was warmed to room temperature for 45 min, then poured into dilute aqueous NH3 saturated with NaCl. The resulting solid was collected, washed with water and recrystallised twice from CH2Cl2/i-Pr2O to give 1-(chloromethyl)-N-[2-(dimethylamino)ethyl]-5-nitro-1,2-dihydro-3H-benzo[e]indole-8-carboxamide (188) (88 mg, 60%) as a red solid: mp 178-180° C.; 1H NMR [(CD3)2SO] δ 8.68 (t, J=5.7 Hz, 1H), 8.22 (d, J=1.2 Hz, 1H), 8.16 (d, J=9.1 Hz, 1H), 7.77 (dd, J=9.1, 1.7 Hz, 1H), 7.72 (s, 1H), 6.41 (d, J=1.7 Hz, 1H), 4.28-4.18 (m, 1H), 3.98 (dd, J=10.9, 3.7 Hz, 1H), 3.84 (td, J=9.7, 2.4 Hz, 1H), 3.75 (dd, J=−11.0, 9.0 Hz, 2H), 3.49-3.37 (m, 2H), 2.45 (t, J=7.0 Hz, 2H), 2.21 (s, 6H).
