実験手順

The compound of step 2 (150 mg, 0.438 mmol) was dissolved in methanol (3 ml), potassium tert-butoxide (73 mg, 0.657 mmol) was added and the mixture was stirred overnight under reflux. Potassium carbonate (60 mg, 0.44 mmol) and iodomethane (124 mg, 0.876 mmol) were then added repeatedly, at intervals of 1 h, with stirring under reflux until completion of the reaction. The volatiles were evaporated in vacuo, the residue was partitioned between EA and 2 N hydrochloric acid, and the aqueous phase was extracted with EA. The combined organic phases were dried over sodium chloride, decanted and evaporated to dryness to yield the title compound.
