Potassium Carbonate → HCID 60341803, compound

Participants

Reaction Steps

2.88 g (15.9 mmol) of 4-methylsulfonylphenol was added to and dissolved in a dimethylsulfoxide solution (30 mL) of 2.12 g (15.9 mmol) of 1-bromo-2-butyne, and then 2.64 g (19.1 mmol) of potassium carbonate was added thereto. After stirred for 6 hours, brine was added thereto and extracted with ethylacetate. The organic layer was washed with brine, and dried over anhydrous magnesium sulfate. 3.39 g (15.11 mmol) of 1-but-2-ynyloxy-4-methanesulfonylbenzene (V-1) was obtained as a roughly-purified product (yield 95%). Its physical properties are shown below.
