Procedure
A 2.2 g. amount of the preceding compound is dissolved in 10.0 ml. of a mixture of formic acid and acetic anhydride (Example 15). The mixture is allowed to remain at room temperature for 3 hours. Water is added and a yellow solid is collected by filtration. The solid is dissolved in dichloromethane. The solution is dried over anhydrous magnesium sulfate and filtered through a hydrous magnesium silicate. The filtrate is concentrated while adding hexane until turbidity occurs. The mixture is cooled and filtered to give 2.1 g. of the product of the Example as a white solid, m.p. 172°-174° C.
