Procedure

This product from Example 3 was added to a solution of methanol saturated with ammonia and was stirred at 25° C. for 2 hours. The solvent was evaporated off, leaving a solid which was stirred in water and filtered. The filtrate was extracted five times with diethyl ether and was acidified. The acidified solution was then extracted with methylene chloride, washed with brine, dried over magnesium sulfate and concentrated to a solid. This residue was extracted with hot hexane from which the title compound crystallized, m.p. 61°-64° C.
