实验步骤: To phosphorous pentachloride (3.3 g, 16 mmol) was added solid heptanesulfonic acid, sodium salt monohydrate (1.75 g, 8 mmol) and the mixture was left to stir overnight under nitrogen. Phosphorous oxychloride was removed by distillation at 150° C. for 3 h. The residue was distilled under reduced pressure (ca. 5 mm Hg) at 135° C. to give ca. 1 g of material which was allowed to cool to room temperature. The precipitated free acid was removed by filtration to afford the title compound as an oil (500 mg, 31%) which was used without further purification. the mixture was left Phosphorous oxychloride was removed by distillation at 150° C. for 3 h The residue was distilled under reduced pressure (ca. 5 mm Hg) at 135° C.
