Procedure
A mixture of 15.0 g. of the above crude product and 85.0 ml. of a mixture of formic acid and acetic anhydride (Example 15) is allowed to remain at room temperature for 2 hours. The reaction mixture is poured into water and filtered to collect the solid. The solid is wahsed with a solution of saturated sodium bicarbonate, then water. The material is dried, dissolved in dichloromethane, then is columnized and recrystallized as above to give 12.0 g. of the desired product as pale yellow crystals. A 5.0 g. amount of this material is recrystallized as above to give 4.70 g. of the desired product, m.p. 164°-166° C.
