preparation example 1

[0069] Preparation Example 1: Synthesis of 2-benzoyl-pyrrole

[0070] Under the protection of nitrogen, 3.00g (44.7mmol) pyrrole was dissolved in 60mL ether, 5.86g (90.1mmol) zinc powder was added under stirring at 0°C, and 5.67g (40.3mmol) benzoyl chloride was slowly added dropwise, and the reaction was completed for 1 hr. After filtration, concentration, and silica gel column chromatography, 4.00 g of a yellow-white solid was obtained, with a yield of 58.0%. 1 H-NMR (400MHz, DMSO-d6) δppm: 12.08 (brs, 1H), 7.81-7.79 (m, 2H), 7.63-7.59 (m, 1H), 7.55-7.51 (m, 2H), 7.23-7.21 ( m, 1H), 6.78-6.77 (m, 1H), 6.27-6.26 (m, 1H).

preparation example 2

[0071] Preparation Example 2: Synthesis of 2-propionyl-pyrrole

[0072] Synthesized with reference to the method of Preparation Example 1 to obtain a white solid with a yield of 61.0%. 1 H-NMR (400MHz, DMSO-d6) δppm: 11.76 (br s, 1H), 7.06-7.04 (m, 1H), 6.97-6.95 (m, 1H), 6.16-6.18 (m, 1H), 2.72-2.89 (q, 2H, J=7Hz), 1.08-1.04 (t, 3H, J=7Hz).

preparation example 3

[0073] Preparation 3: 3,5-Dimethyl-1H-pyrrole-2,4-dicarboxylic acid-2-tert-butyl-4-ethyl ester synthesis

[0074] Under cooling in an ice-water bath, dissolve 8.35g (52.8mmol) of tert-butyl acetoacetate in 15mL of glacial acetic acid, and add dropwise an aqueous solution of sodium nitrite (4.50g of sodium nitrite in 10mL of water) while stirring. over 10°C. After dropping, stir at room temperature for 3 hrs to obtain a light yellow transparent solution, which is set aside for use.

[0075] Dissolve 5.87g (45.1mmol) of ethyl acetoacetate in 20mL of glacial acetic acid and heat to 65°C. Slowly add the light yellow transparent solution prepared above dropwise, and add 10.37g of zinc powder in 5 times. The process is exothermic, and the temperature control does not exceed 80°C. After the addition was complete, the temperature was raised to 75° C. for 1 hr. After cooling to room temperature, a white solid precipitated and was filtered. Petroleum ether was recrystallized to...

Abstract

The present invention provides indolone compounds represented by formula I, and stereoisomers or pharmaceutically acceptable salts or hydrates thereof. The indolone compounds can block signal transduction by VEGF receptors, block the ability of vascular endothelial cells to form new blood vessels, inhibit tumor neoangiogenesis and prevent malignant tumor metastasis.

Description

technical field [0001] The invention belongs to the field of medicine and chemical industry, and relates to an indolinone derivative, its stereoisomer, its cis-trans isomer, or a pharmaceutically acceptable salt thereof. The present invention also relates to a pharmaceutical composition containing the indolinone derivatives, as well as a preparation method and application of the indolinone derivatives. Background technique [0002] Cancer is a disease that seriously threatens human health. Since the advent of the first anticancer drug, nitrogen mustard, in the 1940s, scientists have isolated and extracted several natural products with potential cytotoxic activity from plants. Active compounds, among which vinblastine, etoposide, paclitaxel, etc. have been approved for clinical treatment of cancer. However, these natural product drugs have limited resources, complex molecular structures, difficult chemical synthesis, and difficult large-scale production. Therefore, it is im...
