A 1 N aqueous sodium hydroxide solution (2 ml) was added to the solution, and a reaction was allowed to proceed at room temperature for 3 hr. The reaction solution was adjusted to pH 3 by the addition of 1 N hydrochloric acid. The precipitate was collected by filtration to give 56 mg (yield 76%) of the title compound.
