Reaction Steps

Thionyl chloride (4.2 g) in diethyl ether (10 ml) was added dropwise with stirring at 0°-5° C. to a solution of 2-(5-cyano-2-hydroxyphenyl)-2-methyl-1-propanol (5 g) prepared as in Example 26, and pyridine (5.5 g) in diethyl ether (80 ml). The mixture was stirred for 3 hours at 0°-20° C. Water was then added and the mixture was filtered. The ether solution was then washed with dilute hydrochloric acid, then with aqueous sodium bicarbonate and water (twice), then dried over magnesium sulphate and run down. The residue was recrystallised from ethanol, giving the title product (2.0 g) as white crystals, mp 87°-88° C.
