Reaction Conditions

Reaction Steps

To a mixture of 2-bromo-2-(2-fluoro-4-pyridyl)-1-(3-methylphenyl)ethanone hydrobromide and thiourea (3.03 g, 39.8 mmol) in acetonitrile (50 mL) was added triethylamine (5.2 mL, 37.3 mmol), and the mixture was stirred for 2 hours at 80° C. Aqueous sodium hydrogen carbonate solution was poured into the reaction mixture, and the deposited solid was collected by filtration. The resulted solid was washed with water, then, dried. The crude crystal was recrystallized from ethanol to obtain a title compound (3.67 g, yield 35%).
