    摘要： The present disclosure discloses a method for continuously synthesizing N-Boc-2,5-dihydropyrrole. The method includes the following steps: cis-1,4 dichloro-2 butene is dissolved in an organic solvent, to prepare solution A; urotropine is dissolved in an organic solvent, to prepare solution B; the solution A and solution B are fed into a first continuous reaction device; a product overflow system of the first continuous reaction device is transferred to a second continuous reaction device, and concentrated hydrochloric acid is fed into the same; a product overflow system of the second continuous reaction device is transferred to a third continuous reaction device, and potassium carbonate is fed into the same; a product overflow system of the third continuous reaction device is transferred to a fourth continuous reaction device, and Boc acid anhydride solution is fed into the same; and a product of the fourth continuous reaction device is subjected to continuous solid-liquid separation, concentration and distillation, to obtain N-Boc-2,5-dihydropyrrole. By using technical solution of the present disclosure, the route involving high-risk materials is avoided, and the production capacity and yield are improved in a continuous manner.

    摘要： The disclosure provides a method for preparing nilotinib. The preparation method includes the following steps: performing an aminocarbonylation reaction on a compound A and 3-(4-methyl-1H-imidazole-1-yl)-5-(trifluoromethyl) aniline to obtain an amination product; and performing deprotection treatment of an R group on the amination product to obtain the nilotinib, wherein the compound A has a structure shown in formula I, and in formula I, an R group is selected from benzyl, -COCF 3 , -CHO or -CO 2 R', where an R' group is C 1 ∼C 10 alkyl, C 1 ∼C 3 alkoxy ethyl or C 7 ∼C 19 aralkyl. The preparation method is short in synthesis route and mild in reaction condition. Moreover, with adoption of a special raw material, the preparation method may improve a yield of the nilotinib and simultaneously reduce process cost.

    摘要： The invention discloses an ozonization continuous reaction device, comprising a raw material inlet, a raw material distributing device, one or plurality of single reaction tubes, a product outlet and an air vent. The first end of the raw material distributing device is communicated with the raw material inlet; the first end of one or plurality of single reaction tubes is communicated with the second end of the raw material distributing device; the product outlet is communicated with the second end of the single reaction tube; ozone is conveyed to the single reaction tube via the air vent. The ozonization continuous reaction device provided by the invention realizes the large-scale and continuous production of the ozonization reaction on the basis of guaranteeing security; as the single reaction tube is arranged, the ozone amount and the liquid raw material existing in the single reaction tube in unit time become fewer, the reaction security is greatly improved; in addition, the liquid raw material and the ozone are continuously fed into the reaction device, the exhaust gas and the products are continuously discharged from the reaction device, the accumulation of the ozone is prevented, the security is greatly guaranteed, and the production capacity also can be improved to a higher level.
