Potassium Iodide → (1S)-1-{2-[(2R)-4-(1,2-Dihydro-5-acenaphthylenyl)-2-methylpiperazinyl]ethyl}-3,4-dihydro-1H-2-benzopyran-6-carboxamide

Participants

Reaction Steps

(3R)-1-(1,2-Dihydro-5-acenaphthylenyl)-3-methylpiperazine (0.138 g, 0.55 mmol), 2-[(1S)-6-(aminocarbonyl)-3,4-dihydro-1H-2-benzopyran-1-yl]ethyl methanesulfonate (0.15 g, 0.50 mmol), potassium carbonate (0.138 g, 1.0 mmol), potassium iodide (0.083 g, 1.0 mmol) and acetonitrile (50 mL) were heated under reflux for 1 day with stirring under nitrogen. After cooling to room temperature, the inorganics were filtered off and the solvent evaporated in vacuo. The crude product was purified by preparative LC-MS to give the title compound. M+H=456.
