Participants

Reaction Steps

A 4.8 g. amount of the above compound is dissolved in 25.0 ml. of a mixture of formic acid and acetic anhydride (Example 15). The reaction mixture is allowed to remain at room temperature for 3 hours, then ice water is added to separate a gum. The aqueous phase is decanted and the gum is dissolved in dichloromethane. The solution is dried over magnesium sulfate and passed through a hydrous magnesium silicate. The effluent is evaporated leaving a gum. The gum is dissolved in dichloromethane. The solution is heated and hexane is added until turbidity results. The mixture is cooled and filtered to yield 3.6 g. of the desired product as off-white crystals, m.p. 112°-113° C.
