To 1ml of pyrrolidine is added with stirring 0.100g (0.35 mmol) of the product of Example 3, and 5mg of NH4Cl. The combined reagents were stirred in a sealed tube for 16 hours at room temperature. After this time, an additional 1ml of pyrrolidine and 5mg of NH4Cl was added and the reaction mixture was stirred an additional 16 hours.
