Versuchsvorschrift

DMSO is added to NaH (1-1.8 equiv.) and heated to 65° C. for 1 h. THF is added at the same temperature and heated for another 10 min. After 10 min., the reaction mixture is cooled to 0° C. Trimethylsulfonium iodide (1-1.2 equiv.) is added and the contents stirred for 10 min. after which the solution of 1-(4-fluorophenyl)ethanone (1 equiv.) in THF is added dropwise. After complete addition, the reaction mixture is stirred at RT for 2 h; the reaction is monitored by LCMS. After completion, the reaction mixture was poured in ice water, extracted in diethyl ether, dried over sodium sulfate and concentrated at 25° C. to get the crude product.
