556-90-1, 2-aminothiazol-4(5H)-one is a thiazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,556-90-1
General procedure: To the magnetically stirred solution of 17 (232 mg, 2 mmol) in HOAc (7 mL), was added NaOAc (500 mg, 6 mmol). After 15 min 3,4-dimethoxybenzaldhyde (16a, 400 mg, 2.4 mmol) was added and the reaction mixture was heated under reflux for 72 h. The HOAc was removed under reduced pressure and the resultant solid was washed successively with water, methanol and EtOAc to obtain the desired products as solid. 10.2.1.4 5-(4-Hydroxy-3-nitrobenzylidene)-2-iminothiazolidin-4-one (14d) Orange solid; mp > 200 C; 330 mg, 61% yield; IR (neat) numax = 3164, 2772, 1679, 1604 cm-1; 1H NMR (400 MHz, CD3SOCD3) delta 9.46 (br s, 1H), 9.18 (s, 1H), 8.05 (s, 1H), 7.75 (d, J = 8.74, 1H), 7.55 (s, 1H), 7.24 (d, J = 8.72, 1H); 13C NMR (100 MHz, CD3SOCD3): delta 180.71, 175.57, 153.52, 137.52, 136.46, 129.04, 127.52, 126.27, 125.66, 120.53 HRMS (ESI-TOF): m/z calculated for C10H7N3O4S [M+Na]+, 288.0055; found 288.0046.
As the paragraph descriping shows that 556-90-1 is playing an increasingly important role.
