Methanol → HCID 59954318, compound

Participants

Reaction Steps

To 20 ml of methanol, there were added 0.57 g of (2S, 3aS)-2-acetoxy-5-[4-[(2-phenylbenzoyl)amino]benzoyl]-1,2,3,3a,4,5-hexahydro-pyrrolo [1,2-a]quinoxaline prepared in Example 5 and 0.2 g of anhydrous potassium carbonate and the reaction solution was stirred at room temperature for 15 hours. After concentration of the reaction solution, the resulting residue was diluted with water and then extracted with ethyl acetate. The resulting organic phase was washed with water, dried over anhydrous magnesium sulfate and then concentrated. The resulting residue was recrystallized from ethyl acetate-hexane to give 0.52 g (yield 88.0%) of the title compound.
