Procedure
A mixture of 88 mg of Compound 2, 2 ml of a 1N aqueous solution of sodium hydroxide and 5 ml of ethyleneglycol was heated under reflux for 48 hours. After cooling, the mixture was diluted with water and washed with ether, and the aqueous layer was adjusted to pH 4 with 4N aqueous hydrochloric acid. The resulting precipitate was separated from the mixture by filtration and washed with water to give 44.7 mg (49%) of the product as a white solid.
