実験手順

A stirred solution of 10.1 grams (0.038 mole) of 2,6-dichloro-4-(phenylmethoxy)phenol (known compound) and 8.0 grams (0.058 mole) of potassium carbonate in 150 mL of DMF was cooled to 0–4° C. and 3.7 mL (0.041 mole) of 3-bromopropan-1-ol was slowly added. Upon completion of addition the reaction mixture was allowed to warm to ambient temperature where it was stirred during an 18 hour period. After this time water was added to the reaction mixture, and the mixture was extracted with two 150 mL portions of diethyl ether. The combined extracts were dried with sodium sulfate, filtered, and the filtrate was concentrated under reduced pressure to yield 11.8 grams of residual solid. The NMR spectrum was consistent with the proposed structure.
