Procedure
Stir the oxide from Step A in a mixture of 5 cc of aqueous sodium hydroxide and 10 cc of tetrahydrofuran for 15 minutes. Evaporate the tetrahydrofuran, dilute with water. Filter and acidify the filtrate. Separate the solids by filtration and dry in vacuo at 50° C. Suspend the product in water. Stir overnight, filter and dry at 60° C. to obtain the title product (Yield 605 mg).
