To a clean, dry 500 mL flask equipped with a heating mantle and addition funnel were added 200 mL of DMF and 50.7 g of N-phenylthiomorpholine-S,S-dioxide (0.2 mol, available from Eastman Chemical Company). The reaction vessel was purged with nitrogen and 20.5 mL of phosphorus oxychloride (0.2 mol) were added at such a rate to keep the temperature from exceeding 35 C. The reaction vessel was heated to 80-90 C. and stirred for about 4 h. The reaction mixture was allowed to cool to room temperature and poured into a mechanically stirred ice water mixture (1 L) containing 100 mL of concentrated ammonium hydroxide. A white precipitate formed that was collected by suction filtration and washed with water. The cake was allowed to dry on the filter overnight to give 54.4 g of product. | ||

The mixture was heated to reflux and stirred for 3 h then allowed to cool to about 10 C. using an ice-water bath to crystallize the compound. The crystals were collected by suction filtration, washed with cold water and allowed to dry on the filter overnight to give 8.72 g of light yellow compound. The identity of the product was determined to be the target compound by HPLC-MS and the purity was estimated to be about 88%. The compound exhibited a wavelength of maximum absorption (λmax) at 370.88 nm and a molar absorptivity (ε) of 24,600 as determined by Ultraviolet-Visible light spectroscopy (UV-Vis) in DMF solvent. |
