Reaction Steps

10 g said 4,4′-di(trichloro methyl sulfenyl)benzophenone obtained in step 2, 30 g dichloroethane and 10 g ethanol are added into a 100 ml reaction flask. The solution is heated to react under reflux with nitrogen protection, and is cooled after reacting for 6 hours to precipitate solids. Filtering, and washing with ethanol to obtain 4.4 g white flake crystals, the yield is 85%, and the melting point is 179-182.3° C. 1H-NMR data (solvent CDCl3): δ3.6369 ppm, s, 2H, δ7.3168, 7.3435 ppm, d, 4H, δ7.6384, 7.6650 ppm, d, 4H.
