preparation example Construction

[0115] The present invention also provides the preparation method of above-mentioned compound:

[0116] 1. Preparation of intermediate 1:

[0117] (1) When Y is an oxygen atom,

[0118]

[0119] Dissolve raw material 1, raw material 2, basic catalyst, and Cu(I) in an aprotic solvent, heat until the reaction is complete, cool to room temperature, filter, add water and an organic solvent (such as ethyl acetate, dichloromethane), Separate the liquid, wash the organic phase with a saturated aqueous sodium chloride solution, dry over anhydrous sodium sulfate, filter, concentrate, and purify by column chromatography to obtain an intermediate product, which is then subjected to a conventional deesterification reaction to obtain intermediate 1.

[0120] In this reaction, R' is selected from C 1-6 Alkyl, preferably C 1-4 alkyl, X is halogen; the Cu(I) source refers to copper(I) salts such as copper(I) bromide and copper(I) iodide or copper(I) which are typically more soluble in o...

[0206] Example 1 Preparation of (5-(2,5-dichlorophenoxy)pyrimidin-4-yl)(4-methyl-3,4-dihydroquinoxalin-1(2H)-yl)methanone

[0207]

[0208] 1) Preparation of 5-bromopyrimidine-4-formyl chloride

[0209]

[0210] Dissolve 5-bromopyrimidine-4-carboxylic acid (0.6g, 2.96mmol) in thionyl chloride (10mL), add N,N-dimethylformamide (0.05mL), heat to 90°C and stir for 3 hours . The reaction solution was concentrated to dryness, added toluene (10 mL), and concentrated to dryness again, and the obtained crude product was directly used in the next reaction.

[0211] 2) Preparation of methyl 5-bromopyrimidine-4-carboxylate

[0212]

[0213] 5-Bromopyrimidine-4-carbonyl chloride (0.65 g, 2.94 mmol) obtained in the previous step was dissolved in anhydrous methanol (10 mL), and stirred at 25°C for 16 hours. The reaction solution was concentrated to dryness, and the obtained crude product was washed with petroleum ether to obtain the title compound (0.58g, yield 90.6%)
