Reaction Steps

3,3-Dimethyl-2,3-dihydro-benzo[d]isothiazole 1,1-dioxide was added to KNO3 in H2SO4 cooled to 0° C. and stirred for 15 min. The reaction was warmed to RT and stirred overnight. The mix was poured into ice and extracted with EtOAc (3×), washed with H2O and brine, dried and evaporated to give the product which was used without further purification.
