Procedure

A solution of 0.5 g (1.6 mmol) of material from Example 8 in 5 mL of 2M ammonia in methyl alcohol was stirred at room temperature for 18 hr. To the solution was added 2 mL of concentrated ammonium hydroxide and stirring was continued for 5 hr. The mixture was concentrated in vacuo. Chromatography (25 g of silica gel, 50% ethyl acetate/hexane with 2% methyl alcohol) of the residue afforded 0.03 g (5%) of the title compound.
