| Hazard Information | Back Directory | [Description]
4-chloro-7-Methoxyquinoline-6-carboxaMide is a pharmaceutical intermediate compound used in the preparation of Lenvatinib, an oral multi-receptor tyrosine kinase inhibitor approved by the FDA for the treatment of radioiodine-refractory differentiated thyroid cancer (DTC), unresectable (DTC), unresectable hepatocellular carcinoma (HCC), and advanced renal cell carcinoma (RCC). | [Chemical Properties]
light yellow powder | [Uses]
4-chloro-7-methoxyquinoline-6-amide is a light yellow solid substance, mainly used as an intermediate for lenvatinib. | [Synthesis]
General procedure for the synthesis of 4-chloro-7-methoxyquinoline-6-amide from methyl 4-chloro-7-methoxyquinoline-6-carboxylate: 4.1) Ammonia (200 mL, 5.2 mol) was added to a 500 mL three-necked flask, followed by the addition of Compound IV (10 g, 39.8 mmol) obtained from Step 3.3) to obtain Mixture H; 4.2) Mixture H was was reacted at 60 °C for 4 h. After completion of the reaction, the mixture was cooled to room temperature to obtain mixture I. 4.3) Three extractions were performed by adding dichloromethane to mixture I, resulting in a light yellow solid compound V in 85.17% yield. | [References]
