Reaction Conditions

Reaction Steps

The compound (3 g) of Example 2 was dissolved into acetone and, after methyl iodide (0.8 ml) and potassium hydroxide (3.7 g) were added, the mixture was stirred at 40° C. for 20 hours under heat. After water was added and the reaction mixture was acidified with hydrochloric acid, it was extracted with methylene chloride. The residue obtained by drying methylene chloride layer over anhydrous sodium sulfate and then concentrating under reduced pressure was recrystallized from ethanol-hexane to obtain aimed product (1.25 g) as pale yellow powdery crystals. Melting point: 110°-111° C.
