[2-(2,4-dichlorophenyl)-2-oxoethyl] thiocyanate

Conditions: temp:130.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A 25% hydrogen bromide/acetic acid (60 ml) solution was added to a solution of 2-(2,4-dichlorophenyl)-2-oxoethyl thiocyanate (5.97 g, 24.3 mmol) in acetic acid (60 ml), and the mixture was stirred at 130° C. for 2 hours. Water (120 ml) was poured to the reaction mixture, and crystals were collected by filtration and washed with water to give 6.89 g (92.0%) of the desired product as a solid. were collected by filtration washed with water

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of 2-bromo-1-(2,4-dichlorophenyl)ethanone (7.09 g, 26.5 mmol) and potassium thiocyanate (2.57 g, 26.5 mmol) in ethanol (70 ml) was stirred at 80° C. for 2 hours. After cooling to room temperature, water (70 ml) was poured to the reaction mixture, and crystals were collected by filtration and washed with water to give 5.97 g (91.7%) of the desired product as a solid. were collected by filtration washed with water
