실험 절차

A mixture of N-(3-acetylaminophenyl)thiourea (0.84 g) and 2-bromoacetophenone (0.84 g) in ethanol (10 ml) was refluxed for 15 minutes. After evaporation of the solvent, 3N hydrochloric acid was added thereto and the mixture was refluxed for 30 minutes. The mixture was made basic with sodium bicarbonate and extracted with ethyl acetate. The organic solution was washed with water and brine, dried over magnesium sulfate and concentrated. The residue was crystallized from ethanol to give 3-(4-phenylthiazol-2-yl)aminoaniline (0.88 g).
