[0062] The present invention also provides a preparation method of the compound shown in formula 1, the preparation method comprising the following steps:
[0063] Step 1. react the compound shown in formula 2 with the compound shown in formula 3 to prepare the compound shown in formula 4, as shown in following reaction formula 1:
[0064] [Reaction 1]
[0065]
[0066] In Equation 1, R 1 , R 2 , r, s are as defined in formula 1, X represents halogen, preferably chlorine or bromine;
[0067] The reaction is carried out in the presence of a base, which includes inorganic bases such as sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate, sodium bicarbonate or potassium bicarbonate; and organic bases such as triethylamine, pyridine or piperidine.
[0068] Step 2. react the compound shown in formula 4 with the compound shown in formula 5 to prepare the compound shown in formula 1, as shown in following reaction formula 2:

Embodiment 1
[0081] Example 1: (Z)-3-((1H-benzo[d]imidazol-7-yl)methylene)-5-methyl-6-(pyridin-2-yl)indoline-2- Ketone (Compound I)
[0082]
[0083] Step 1: Put 1H-benzo[d]imidazole-7-carbaldehyde (2.19g, 15.0mmol) in a 500ml eggplant-shaped bottle, add 150ml of absolute ethanol to dissolve, then add 6-chloro-5-methylind Indolin-2-one and 2ml triethylamine were reacted at room temperature for 3 hours, and a large amount of precipitation appeared. Suction filtration, washing with a small amount of absolute ethanol, drying to obtain yellow solid (Z)-3-((1H-benzo[d]imidazol-7-yl)methylene)-6-chloro-5-methylindole Lin-2-one 4.15g, yield 89.2%, content 98.1%. ESI-MS: 310.07[M+H] + .
[0084] Step 2: Add (Z)-3-((1H-benzo[d]imidazol-7-yl)methylene)-6-chloro-5-methylindoline-2 to a dry Schlenk reaction tube -ketone (3.09g, 10.0mmol), pyridin-2-ylboronic acid dimethyl ester (1.66g, 11.0mmol), tetrakis(triphenylphosphine)palladium (0.12g, 0.1mmol), Na 2 CO 3 (2.12g, 20.0mmol), under the p...
Embodiment 2
[0088] Example 2: (Z)-5-(hydroxymethyl)-3-((5-(methylsulfonyl)-1H-benzo[d]imidazol-7-yl)methylene)-6-( Pyrimidin-2-yl)indolin-2-one (Compound II)
[0089]
[0090] According to the method of Example 1, with 1-(5-(methylsulfonyl)-1H-benzo[d]imidazol-7-yl)-formaldehyde instead of 1H-benzo[d]imidazole-7-formaldehyde, use 6-Bromo-5-(hydroxymethyl)indolin-2-one instead of 6-chloro-5-methylindolin-2-one, pyrimidin-2-ylboronic acid dimethyl ester instead of pyridin-2- Dimethyl boronic acid was used to obtain the title compound as a white solid in a total yield of 63.9% over two steps.
