Thiourea → HCID 58442508, compound

Participants

Reaction Steps

A mixture of 2-bromo-1-(4-chloro-2,6-dimethylphenyl)ethanone (6.54 g, 25.0 mmol) and thiourea (1.90 g, 25.0 mmol) in 95% EtOH (35.7 mL) was heated at reflux for 60 min. The solution was concentrated and added with water (50 mL) followed by 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-(4-chloro-2,6-dimethylphenyl)thiazol-2-amine (4.30 g) as white solids in 72% yield: 1H NMR (500 MHz, DMSO-d) δ 7.16 (s, 2 H), 6.43 (s, 1 H), 2.10 (s, 6 H).
