The effects of polyethyleneglycol dialkyl ethers as solvents in the reaction of potassium 3-aminophenoxide with isopropyl chloride were studied. The reactions using the polyethyleneglycol dialkyl ethers as solvents gave O- isopropylated 3-aminophenol in higher yields than using small amounts of dibenzo-18- crown-6 or the polyethyleneglycol dialkyl ethers as solvents.
