Reaction Steps

A mixture of 2-chloro-1-(2,4,6-trifluorophenyl)ethanone (9.04 g, 43.5 mmol) and thiourea (3.51 g, 46.1 mmol) in 95% EtOH (50 mL) was heated at reflux overnight. The solution was concentrated and mixed with water (100 mL) and saturated aqueous Na2CO3 (5.0 mL). The solids were filtered and dried under vacuum to give 4-(2,4,6-trifluorophenyl)thiazol-2-amine (9.71 g) as pink-white solids in 97% yield: 1H NMR (500 MHz, DMSO-d6) δ 7.26-7.22 (m, 2 H), 7.09 (s, 2 H), 6.77 (s, 1 H).
