Procedure
A 2 mol/L aqueous sodium hydroxide solution (20 mL) was added to an ethanol (10 mL) solution of Compound 1 (1.5 g, 4.2 mmol), and the mixture was stirred overnight while refluxing and heating. Ethanol was distilled off under a reduced pressure, and 6 mol/L hydrochloric acid was added to the resulting residue. The precipitated crystals were collected by filtration, and sufficiently washed with water. The crystals were dried over phosphorus pentoxide at 50° C. under a reduced pressure, to give 0.96 g (67%) of the captioned compound.
