실험 절차
Potassium t-butoxide (2.6 g) was added to a solution of the product of stage (b) in dimethylformamide (30 ml) with stirring and cooling. After 10 minutes, this solution was treated with dimethyl sulphate (2.8 g) and stirring was continued for 4 hours. Addition to ice/water/ether and filtration gave 2.3 g of desired product, mp 101°-103° C.
