Reaction Conditions

Reaction Steps

To a suspension of 79 g of the product of Example 1 in 1500 ml of benzene under a N2 atmosphere, cooled at 20° to 30° C. with external cooling, was added, portionwise, 60.2 g of phosphorous pentachloride. After stirring at 25° C. for about 24 hours, the suspension was warmed at 40° C. for about four hours, then cooled to 25° C. and filtered. The filtrate was evaporated at less than 40° C. under vacuum, and residue was chromatographed on silica gel with methylene chloride at eluant to yield 47 g of the subject compound as a crude yellow oil.
