Versuchsvorschrift

8.1 g (0.0251 mol) of the product of Step (2) was added to dimethylsulfoxide (125 ml) and heated to 100° C. and dissolved. After cooling the solution to room temperature, 5.2 g (0.0375 mol) of potassium carbonate and 5.6 g (0.0375 mol) of sodium iodide and 6.7 ml (0.0375 mol) of benzhydrylchloride were added thereto, and the mixture was reacted at room temperature for 18 hours under stirring. To the reaction solution, ice water was gradually added, and formed precipitates were collected by filtration, washed sequentially with water and ethyl ether/n-hexane (2/1), and dried to obtain 12.3 g (yield: 100%) of the above identified compound.
