Procedure

A solution of the product from Example 12 (0.98 g, 2.72 mmol) in 3N HCl (35 mL) was treated with oxalic acid (0.36 g, 2.86 mmol) and refluxed for five hours. When cool to room temperatures the precipitate was filtered, suspended in water (70 mL) and basifyed to pH 8. The solids were filtered, and dried to give the title compound (0.68 g, 60%) as a brown solid, mp=288-293° C.
