Reaction Steps

3.05 g of the product from Example 1 and 2.5 ml of pyrrolidine are boiled in 50 ml of dioxane for 3 hours. The mixture is concentrated in vacuo and the residue is taken up in water. The mixture is rendered neutral with 1N HCl. The solid which has precipitated out is filtered off with suction, dried and stirred with acetonitrile. 1.8 of the title compound with a melting point of 274°-6° C. are obtained.
