실험 절차

33.5 g of thiourea are added to 30 g of 4-methoxyacetophenone, 56 g of iodine are added and the mixture is kept at 100° C. for 5 hours. The reaction mixture is discharged onto water, powdered, washed several times with ether then with ammonia solution and finally with water, and dried. 37.8 g of 4-(4-methoxyphenyl)-thiazol-2-yl-amine of melting point 194°-205° C. are obtained.
