Procedimiento

A mixture of 12.06 g of the product of Example 3 and 60 ml of 2N sodium hydroxide is stirred for one hour. The resulting yellow solution is acidified with 65 ml of 2N hydrochloric acid to give a colorless gum which solidifies on standing. The mixture is filtered and the separated product is washed with water until the washings are neutral. The material is dried in vacuo, then is pulverized, and dried again to give 8.36 g of the product of the Example as a colorless powder.
