To a solution of (R)-4-(piperidin-3-oxy)-9-(2-trimethylsilanyl-ethoxymethyl)-9H-dipyrido[2,3-b;4′,3′-d]pyrrole-6-carbonitrile (84 mg, 0.20 mmol) in acetonitrile (1.0 mL) was added iodoethane (24 uL, 0.30 mmol), and the mixture was heated at 50° C. for 18 hours. The cooled reaction mixture was diluted with saturated aqueous sodium bicarbonate solution (50 mL) and methylene chloride (50 mL). The organic layer was separated, dried over sodium sulfate, filtered, concentrated in vacuo, and purified flash chromatography (silica, 4 g, ISCO, 1-20% methanol in methylene chloride) to afford the title compound as a yellow oil, which was used in the next step without any further purification (46 mg, 51%).
