Participants

Reaction Steps

A mixture of 1-chloropropan-2-one (1.01 g, 11 mmol), 1-(5-bromo-4-(2,6-difluorophenoxy)pyridin-2-yl)thiourea (3.24 g, 9.0 mmol), triethylamine (1.41 g, 14 mmol) and ethanol (15 mL) is heated at reflux for 16 hours. The reaction mixture is cooled and partitioned between ethyl acetate and water. The organic layer is washed with water and brine, dried and concentrated. The residue is purified via chromatography to afford N-(5-bromo-4-(2,6-difluorophenoxy)pyridin-2-yl)-4-methylthiazol-2-amine.
