Participants

Reaction Steps

To a solution of the compound (0.455 g) obtained in Example 13 in ethyl acetate (3 mL) was added 4N hydrogen chloride/ethyl acetate solution (3 mL), and the mixture was stirred at room temperature for 24 hr with heating. The reaction mixture was concentrated under reduced pressure, ethyl acetate was added to the residue, and the mixture was made basic with 2N aqueous sodium hydroxide solution. The organic layer was separated, washed with water, and the solvent was evaporated under reduced pressure to give the title compound (0.27 g, 75%) as a white powder.
