[0056] Among them, R, R 3 , R 4 , R 5 as mentioned earlier.
[0057] The present invention is described in detail with the following examples. However, it should be understood that the present invention is not limited to the specific recited examples below.
Embodiment 1
[0058] Example 1: 1-(3,5-difluorophenyl)-3-{4-{[4-(3-methoxypropoxy)-3-methylpyridin-2-yl]methoxy }phenyl}urea (compound Z01)
[0059] Step A: Preparation of 4-(3-methoxypropoxy)-3-methyl-2-[(4-nitrophenoxy)methyl]pyridine
[0060] Add 4-nitrophenol (13.91g, 0.10mol), 2-chloromethyl-3-methyl-4-(3-methoxypropoxy)pyridine hydrochloride (26.62g , 0.10mol) and absolute ethanol (200mL). A 3 mol / L sodium hydroxide aqueous solution (100 mL) was added dropwise at room temperature. After the dropwise addition, react at room temperature for 6h. After the reaction, part of the ethanol was distilled off under reduced pressure, and 200 mL of water was added to the residue to precipitate a large amount of white solid. The filter cake was filtered with suction, washed with water, and dried in air to obtain 30.68 g of white solid, with a yield of 92.6%. The product was used directly in the next step without further purification.

Description
technical field [0001] The invention belongs to the technical field of medicine, and relates to 1-aryl-3-{4-[(pyridin-2-ylmethyl)thio]phenyl}urea compounds and a preparation method thereof, and also relates to its function as BRaf kinase, vascular Endothelial growth factor receptor-2 (VEGFR-2), platelet-derived growth factor receptor-β (Platelet-derived growth factor receptors-β, PDGFR-β) and T-LAK cell-derived protein kinase (T-LAK cell-originated protein kinase, TOPK) inhibitor application. Background technique [0002] In recent years, with the continuous elucidation of tumor pathogenesis and the continuous discovery of anti-tumor targets, multi-target inhibition of tumor signal transduction has become an important direction for the development of tumor drugs. Compared with single-target drugs and multiple single-target drugs in combination, multi-target drugs have more advantages: drug interactions can be avoided, adverse reactions can be reduced, and the therapeutic ef...
