Reaction Steps

First, 38.5 gm of sodium phenyl sulfinate and then 3.85 gm of sodium carbonate were introduced into 116 cc of methanol and 44 gm of freshly prepared 1-bromo-2-cyclohexylidene-ethane were added dropwise over 30 minutes and at room temperature. The reaction mixture was then agitated for 1 hour and 30 minutes at room temperature after which the reaction mixture was poured into 400 cc of ice water. The precipitate formed was vacuum filtered, washed with water and dried. The raw product thus obtained was dissolved at high temperature in a mixture consisting of methylene chloride and methanol. The solution obtained was dried over magnesium sulfate, concentrated to a small volume and admixed with isopropyl ether. The precipitate formed was vacuum filtered and dried to obtain 36.4 gm of (2-cyclohexylidene-ethyl)-phenyl sulfone, having a melting point of 70° C. A sample of this product, crystallized from isopropyl ether, had a melting point of 70° C.
