| Hazard Information | Back Directory | [Description]
N-(2-Chloro-6-methylphenyl)-2-[(6-chloro-2-methyl-4-pyrimidinyl)amino]-5-thiazolecarboxamide is a pharmaceutical intermediate compound used as a synthetic intermediate for dasatinib. Dasatinib is a targeted anticancer drug used to treat chronic myeloid leukaemia (CML) and Philadelphia chromosome-positive acute lymphoblastic leukaemia (ALL). It is also a receptor and non-receptor Tyk (tyrosine kinase) inhibitor, which plays an important role in certain cancers and fibrotic diseases. | [Chemical Properties]

General procedure for the synthesis of N-(2-chloro-6-methylphenyl)-2-[(6-chloro-2-methyl-4-pyrimidinyl)amino]-5-thiazolecarboxamide from 4,6-dichloro-2-methylpyrimidine and 2-amino-N-(2-chloro-6-methylphenyl)thiazole-5-carboxamide: To 80 mL of tetrahydrofuran, cooled to -25 °C, was added 8.73 g of potassium hydride (30 wt%, 65.38 mmol) and stirred for 10 minutes; 5.00 g of 2-amino-N-(2-chloro-6-methylphenyl)thiazole-5-carboxamide was slowly added and the temperature was maintained at -25 °C; followed by the addition of 3.65 g of 4,6-dichloro-2-methylpyrimidine to a tetrahydrofuran solution (7 mL), the temperature was maintained stable and the reaction mixture was stirred for 4 hours at -10 °C. After completion of the reaction, 1 M hydrochloric acid was slowly added to quench the reaction, pH was adjusted to 6, the temperature was controlled at 0-5 °C for 2 h. Crystallization was carried out by centrifugation and washed with tetrahydrofuran. The crude product was obtained as 7.27 g in 98.7% yield and 99.95% purity (HPLC) with a maximum single heterogeneous content of 0.03%. | [References]
