Procedure
12.5 g (0.037 mol) of the sodium benzenesulfonate obtained in Step (a) above was stirred in 74 ml of acetonitrile, to which were added dropwise 14 ml of phosphorus oxychloride and then 14 mol of N,N-dimethylacetamide, and the mixture was heated at 50° C. with stirring for 1.5 hours. After cooling, the reaction mixture was added to 300 ml of ice water and the crystals thus-precipitated were collected by filtration. Yield: 11.9 g (96%).
