Versuchsvorschrift
A 3.0 g. amount of the preceding product is dissolved in 10 ml. of a mixture of formic acid and acetic anhydride (Example 15). The mixture is allowed to remain at room temperature for 3 hours, then is poured into ice water to separate a partial gum and solid. This material is collected, dissolved in dichloromethane and filtered through a short column of a hydrous magnesium silicate. The effluent is concentrated while adding hexane to separate 3.1 g. of the product of the Example as light yellow crystals, m.p. 140°-142° C.
