Procedure

To a solution of the compound (0.10 g) obtained in step 1 in ethanol (1 mL) was added hydrobromic acid-ethanol solution (1 mL), and the mixture was stirred at room temperature for 4 hr. The solvent was evaporated under reduced pressure, and the aqueous layer was made basic with ethyl acetate and aqueous sodium hydroxide solution. The organic layer was washed with brine and dried, and the solvent was evaporated under reduced pressure. Ethyl acetate was added to the residue, and hydrobromic acid-ethanol solution was added. The precipitate was collected by filtration to give the title compound (0.03 g, 25%) as a white powder.
