Reaction Steps

To a solution of 2′,6′-dihydroxy-acetophenone (500 mg, 3.28 mmol) in dimethylformamide (20 ml) were added potassium carbonate (680 mg, 4.93 mmol) and 1-bromo-3-chloropropane (0.34 ml, 3.45 mmol) and the mixture was stirred at 70° C. for 4 h. Water was added and the organics were extracted with ethylacetate, washed with brine, dried over sodium sulfate and concentrated to dryness. The residue was purified by flash chromatography over silica gel (gradient cyclohexane/ethyl acetate: 0-15%) to yield 6′-(3-chloropropoxy)-2′-hydroxy-acetophenone (348 mg, 46%) as a pale yellow solid. To a solution of 6′-(3-chloropropoxy)-2′-hydroxy-acetophenone (345 mg, 1.50 mmol) in acetonitrile (15 ml) was added potassium carbonate (416 mg, 3.0 mmol) and morpholine (0.396 ml, 4.52 mmol). The mixture was stirred for 18 hours at room temperature then 60° C. for 3 days. Water was added and the organics were extracted with ethylacetate, washed with brine, dried over sodium sulfate and concentrated to dryness. The residue was purified by flash chromatography over silica gel (gradient ethyl acetate/methanol: 0-10%) to yield 2′-hydroxy-6′-(3-morpholino-4-yl-propoxy)-acetophenone (171 mg, 40%) as an orange oil that solidified.
