Reaction Steps

(±)-Trans-7-[4-(1H-indol-3-yl)-2,5-dioxo-pyrrolidin-3-yl]-3,4-dihydro-1H-[1,4]diazepino[6,7,1-hi]indole-2-carb oxylic acid benzyl ester (161 mg, 0.31 mmol) and 10% palladium on carbon (100 mg) in anhydrous methanol (15 ml) were stirred under 1 atmosphere of hydrogen for 16 hours. The catalyst was then filtered through a bed of Celite and the filtrate evaporated to dryness to yield (±)-trans-3-(1H-indol-3-yl)-4-(1,2,3,4-tetrahydro-[1,4]diazepino[6,7,1-hi]indol-7-yl)-pyrrolidine-2,5-dione as an off white solid (95 mg). 1H NMR (DMSO-d6) 400 MHz δ: 11.04 (d, 1H, J=1.6 Hz), 7.35-7.42 (m, 4H), 7.24 (dd, 1H, J=2.8 and 5.6 Hz), 7.09 (t, 1H, J=7.2 Hz), 6.89-6.98 (m, 3H), 4.52 (dd, 2H, J=7.2 and 24.8 Hz), 4.11 (s, 2H), 4.07-4.10 (m, 2H), 3.14-3.17 (m, 2H).
