実験手順

To a solution of commercially available 5-bromo-6,7-dihydro-5H-benzo[1,2,5]oxadiazol-4-one (1.1 g, 5.1 mmol) in absolute ethanol (60 mL) was added thiourea. The reaction mixture was stirred at 60° C. for overnight and then concentrated. The residue was triturated in hexanes to afford 1.3 g (90%) of the title compound. MS (ESI+) m/z 195 (M+H)+.
