Paragraph 0026-32, (2017/07/21)
The invention belongs to the technical field of medicine synthesis, and especially relates to a synthetic method of an anti-cancer drug ceritinib intermediate 1-amino-2-(isopropyl sulfonyl)benzene. The synthetic method comprises the following steps: employing o-fluoronitrobenzene, sodium hydride and isopropyl mercaptan to synthesize a 2-(isopropyl sulfide) nitrobenzene crude product, then directly reducing the crude product to iron powder, forming salt to obtain the 2-(isopropyl sulfide) aniline hydrochloride, and finally dropping hydrogen peroxide for oxidation in 2-(isopropyl sulfide) aniline hydrochloride for oxidation, forming salt, and dissociating to obtain a target product. The synthetic method has the advantages of simpleness, little sewage amount, low energy consumption, low production cost, and the product has the advantages of high purity, high yield, and easy industrial production, and is suitable for further popularization and application.
