Reaction Steps

To a solution of (14h) (69.91 g., 0.375 mol) and diethyl bromomalonate (79.9 ml., 0.468 mol) in 2-butanone (400 ml.) was added freshly powdered anhydrous potassium carbonate (51.78 g.). The suspension was stirred vigorously and heated at reflux for 4.5 hours, then filtered and evaporated to dryness. The oil obtained was redissolved in carbon tetrachloride and filtered, then evaporated and recrystallized from chloroform with hexane to yield 79.6% of (15h), m.p. 115.5°-117° C.
