실험 절차
A 25% hydrogen bromide/acetic acid (40 ml) solution was added to a solution of 2-(2,3-difluorophenyl)-2-oxoethyl thiocyanate (5.67 g, 26.6 mmol) in acetic acid (40 ml), and the mixture was stirred at 130° C. for 2 hours and at room temperature for 1 hour. Water was poured to the reaction mixture, and crystals were collected by filtration and washed with water to give 6.74 g (91.8%) of the desired product as a solid.
