Procedure

A 4.50 g portion of p-hydroxyphenylacetone, prepared above, was dissolved in 80 mL of anhydrous dimethylformamide under a dry nitrogen atmosphere. With stirring 1.26 g of sodium hydride (as a 60% dispersion in oil) was added to the solution. After 3 minutes, 9.40 g of 1-chloro-3-iodopropane was quickly added. After stirring for approximately 18 hours, the reactionwas diluted with 300 mL hexane and 100 mL diethyl ether. The resulting mixture was washed with distilled water, 5% sodium hydroxide solution, andbrine. The remaining organic phase was dried and evaporated to dryness in vacuo. The yellow oil was purified by column chromatography over silica gel, using 22% ethyl acetate and 78% hexane. Appropriate fractions were pooled and solvents removed in vacuo to yield 3.06 g of a yellow oil.
