Procedure
A solution of 9.2 g of Intermediate III and 7.8 g of thionyl chloride in 75 ml of toluene was refluxed for 3 hours. After cooling to 20°-25° C. the resultant crystal was collected by suction filtration, washed with acetone and dried in vacuo to give 6.8 g of the title compound, m.p. (190) 196°-198° C. after recrystallization from toluene.
