Reaction Steps

In a round-bottomed flask, 500 mg of 1-(5-Hydroxy-2,3-dihydro-1,4-benzodioxin-6-yl)ethan-1-one was dissolved in 1 mL of DMF. To this solution was added, 414 mg of K2CO3, and methyl iodide (1 mL, excess). The reaction was heated to 80° C. overnight. The reaction was poured into water and extracted with diethyl ether. The organic extract was washed with brine, dried (Na2SO4), filtered, and concentrated to afford 0.38 g (70%) of the acetophenone 8.
