Reaction Steps

A solution of 10.00 g (0.0409 mol) of 2-(2',4'-dimethylphenyl)-5,5-dimethyl-1,3-cyclohexanedione, 21.42 g (0.155 mol) of anhydrous potassium carbonate, 17.59 g (0.124 mol) iodomethane, and 500 ml of anhydrous acetone was refluxed overnight. The reaction mixture was then cooled to room temperature, filtered, and the acetone removed. The residual solid was taken up in 250 ml of CH2Cl2, washed with water, 0.25 N NaOH, 1 N HCl, and water again. The solution was dried (MgSO4) and the solvent removed. The resulting solid was recrystallized from isopropyl ether to give 7.60 g (72% yield) of a white crystalline solid, m.p. 122°-23° C. The compound prepared by the above synthesis has the following structure: ##STR27##
