실험 절차
Sodium (3.7 g) was added to absolute methanol (400 ml) under a nitrogen atmosphere. To this solution was added the product (28.5 g) from step (iii) and the mixture was stirred at 65° C. for 9 h. The mixture was concentrated in vacuo and 500 ml of water added. The aqueous phase was extracted with EtOAc and washed with brine and dried. The subtitle compound was obtained after crystallisation from diethyl ether. Yield 14.2 g.
