Procedure

A mixture of 79 (8.8 g, 0.031 m) in 3N HCl (70 ml) and acetone (70 ml) was refluxed for 45 minutes. Acetone was removed under reduced pressure and the aqueous mixture rendered alkaline with K2CO3. The solid was collected and dried in a vacuum oven at 60° C. to yield 80 (5.14 g, 67%, m.p. 196°-199° C.).
