実験手順

A 25% hydrogen bromide/acetic acid (25 ml) solution was added to a solution of 2-(2,4-difluorophenyl)-2-oxoethyl thiocyanate (3.39 g, 15.9 mmol) in acetic acid (25 ml), and the mixture was stirred at 130° C. for 2 hours and stirred 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 3.23 g (73.6%) of the desired product as a solid.
