Participants

Reaction Steps

A solution of 9-benzenesulfonyl-5-(1-ethyl-piperidin-4-ylmethyl)-9H-dipyrido[2,3-b;4′,3′-d]pyrrole-6-carbonitrile (200 mg, 0.4 mmol) and triethylamine (4 mL) in methanol (40 mL) was stirred at ambient temperature for 6 days. The mixture was concentrated in vacuo and the residue purified by flash chromatography (silica, 2 g column, Si-SPE, 0-20% MeOH in DCM). The resultant material was triturated with acetonitrile and methanol to afford the title compound as a white solid (65 mg, 51%). 1H NMR (DMSO-D6, 400 MHz): 12.85 (s, 1H), 8.90 (s, 1H), 8.70 (dd, J=4.8, 1.5 Hz, 1H), 8.65 (dd, J=8.0, 1.6 Hz, 1H), 7.46 (dd, J=8.0, 4.8 Hz, 1H), 2.86-2.77 (m, 2H), 2.24 (q, J=7.2 Hz, 2H), 1.84-1.58 (m, 5H), 1.54-1.40 (m, 2H), 0.95 (t, J=7.1 Hz, 3H). LCMS (Method H): RT=4.56 min, M+H+=320.
