Reaction Steps

Tetrabutylammonium bromide (635 mg), 6N soda (13 ml), and methyl sulfate (5.59 ml) are added to a solution of Compound 1 (5.31 grams) in THF. After 1 hour 30 minutes of stirring at 25° C., the solution is evaporated under vacuum, dissolved in water, and extracted with ethyl acetate. After washing with water, drying, filtration and evaporation under vacuum, a residue is obtained which is dissolved in ether and recrystallized from a 60/40 mixture of dioxane and hexane, to provide Compound 2 (3.97 grams; yield 71%).
