Reaction Steps

To a cold (0° C.) suspension of 9-hydroxyfluorene (49 g) in benzene (650 mL) was added thionylchloride (70 mL). This solution was allowed to stir while warming up to room temperature overnight. The benzene was distilled off and the product was recrystallized from isopropylether to give 41 g of the title compound as a white solid: m.p. 87°-89° C.
