9.0 g (54 mmol) of benzothiophene 1,1-dioxide and 7.9 g (108 mmol) of n-butylamine were suspended in 130 ml of ethanol, and the mixture was heated at reflux temperature for 3 h. The reaction mixture was concentrated under reduced pressure, giving 14.5 g of butyl-(1,1-dioxo-2,3-dihydro-1H-benzo[b]thiophen-3-yl)-amine as an oil.
