Reaction Steps

A mixture of 2-bromo-1-(2,6-dimethyl-4-(methylthio)phenyl)ethanone (4.64 g, 17.0 mmol) and thiourea (1.29 g, 17.0 mmol) in 95% EtOH (24.3 mL) was heated at reflux for 120 min. The solution was concentrated and added with water (50 mL) and saturated aqueous Na2CO3 (4.0 mL). The resultant precipitate was filtered and recrystallized in toluene (30 mL). The solids were filtered and dried under vacuum to give 4-(2,6-dimethyl-4-(methylthio)phenyl)thiazol-2-amine (1.9 g) as light yellow solids in 45% yield: 1H NMR (500 MHz, CDCl3) δ 6.97 (s, 2H), 6.26 (s, 1H), 2.47 (s, 3H), 2.15 (s, 6H).
