反応手順

Thionyl chloride (3.6 ml., 49.3 mmol) was added rapidly to a stirred solution of 3-[2(E)-(7-chloroquinolin-2-yl)ethenyl]benzyl alcohol (Example 6a part (ii)) (11.7 g, 39.5 mmol) in 1,2-dichloroethane (300 ml) at 50° C. giving an immediate yellow precipitate. The mixture was stirred for 1 hour and cooled to room temperature then the mixture was shaken with saturated sodium bicarbonate solution (400 ml) and methanol (50 ml) to give two clear phases. The aqueous phase was extracted with dichloromethane and the combined solvent phase was dried and evaporated.
