Potassium Carbonate → HCID 12851639, compound

Participants

Reaction Steps

A mixture of 5.80 g of 1-(2,4-dihydroxy-3-propylphenyl)ethanone, 3.6 ml of 3-bromo-1-propanol and 8.3 g of anhydrous potassium carbonate in 50 ml of anhydrous dimethyl formamide was stirred at 75° for 64 hours. The reaction mixture was concentrated in vacuo, the residue was acidified and extracted with ethyl acetate. The extract was dried over magnesium sulfate and concentrated in vacuo to 8.7 g of an oil which was chromatographed on 150 g of silica gel. Elution with 40% ethyl acetate-toluene gave 2.84 g which was crystallized from ether-hexane to yield 2.14 g, mp 57°-59°, (28% yield) of 1-[2-hydroxy-4-(3-hydroxypropoxy)-3-propylphenyl]ethanone, the titled compound.
