Versuchsvorschrift

The product from stage (b) (7.9 g) was dissolved in dichloromethane (50 ml) and was treated with pyridine (2.7 g), then with thionyl chloride (4.2 g) in dichloromethane (5 ml) dropwise with stirring at 5°-10° C. After 3 hours stirring at room temperature, the solution was washed with water, dilute hydrochloric acid, aqueous sodium bicarbonate solution and water again, dried and run down to give the desired product as a brown oil which was recrystallise from ethanol to give pure product, mp 91°-93° C.
