Reaction Steps

The product from (b) (42 g, 0.12 mol) was added portionwise to a suspension of potassium t-butoxide (21.3 g, 0.19 mol) in diethyl carbonate (56.6 g, 0.48 mol) at 75° C. over 10 minutes. Heating was continued at 95° C. for 1 h. After cooling to 50° C., the suspension was poured into cold water (1 liter) and extracted with ethyl acetate (3×400 ml). The organic solution was dried and evaporated under reduced pressure to give the product (47 g, 93%) as a yellow waxy solid which was used in the next reaction without further purification.
