Sodium Acetate → HCID 13922872, compound

Participants

Reaction Steps

To a mixture of 5-bromomethyl-2-sulfamoylbenzo[b]thiophene (3.06, 0.01 mol), anhydrous sodium acetate (0.98 g, 0.01 mol) and glacial acetic acid (15 ml) was added three drops of triethylamine. The mixture was heated and the resulting solution was stirred at reflux for 6 hours and was left at room temperature over night. The acetic acid was removed in vacuo and the residual gum was diluted with 25 ml of ice water. The product was extracted into 3×50 ml of ether. The combined extracts were washed with water, dried over anhydrous Na2SO4, filtered and concentrated in vacuo to give 2.5 g of yellow solid (88% yield). Recrystallization from chloroform gave material with a m.p. 113°-115° C.
