Procedure

A solution of the product from Example 9 (0.22 g, 0.33 mmol) in 5 mL Et2O was treated with a solution of oxalic acid (0.13 g, 1.03 mmol) in 1 mL of ethanol. The resulting solution was triturated with 5 mL of Et2O and collected by filtration. The solid collected was washed with Et2O and dried (P2O5) under vacuum to give the title compound (0.28 g, 91%) as a white solid, mp=111-148° C.
