实验步骤: A solution of p-chloromethyl phenol in acetonitrile (Example 12) was reacted with equimolar dimethyl amine and equimolar 2,4-pentanedione by stirring together for 1 hour. The reactive mixture was diluted with water, acidified with hydrochloric acid, extracted with ether, and then the ether extract was dried with sodium sulfate. The residual oil was triturated with benzene to yield 78% of 3(4' hydroxybenzyl)-2,4-pentanedione, M.P. 93°-94.5° C. Infrared and nuclear magnetic resonance spectra confirmed the identity of the product. extracted with ether the ether extract was dried with sodium sulfate The residual oil was triturated with benzene
