Procedure

A mixture of the product from Example 22 (8.8 g, 24.7 mmol) in 100 mL 6 N HCl was heated at reflux for 2.5 h. After cooling in an ice bath, the yellow precipitate was collected by filtration, washed with diethyl ether and air dried to give 7.08 g of a yellow solid. The filtrate was concentrated to give a red orange solid (2.1 g).
