Reaction Conditions

Reaction Steps

A mixture of 8.75 g. (0.023 mole) of the product from Example 7 and 25 g. of pyridine hydrochloride was prepared. The mixture was refluxed in a 220° C. oil bath for 30 minutes. The hot reaction mixture then was poured over ice, and the resulting mixture was added to a blender. The resulting yellow crystals were collected on a filter, washed with water, and vacuum dried at 100° C. This treatment caused some resinification of the sample. The residue was recrystallized from a mixture of ethyl acetate and benzene to obtain 5.3 g. (65 percent) of the title compound as bright yellow crystals, m.p. 198°-200° C.
