Synthetic example 1

[0192]

[0193] Make 1,1-dimethyl-2-propyl acetate (2-methyl-3-butyn-2-yl acetate) (51.5g, 408.2mmol), copper (I) chloride (2.02g , 20.4mmol), triethylamine (56.6mL, 408.2mmol) and 1-methylpiperazine (54.3mL, 489.9mmol) in THF (480mL) were reacted under reflux for 2 hours. The reaction solution was concentrated, tert-butyl methyl ether (200 mL) was added to the residue, and the product was extracted with dilute hydrochloric acid. While stirring the extract under ice cooling, 6N aqueous sodium hydroxide solution was added until the aqueous layer became basic, and extracted with dichloromethane (500 mL×1, 150 mL×3). The extract was washed with 14% ammonia water and then with saturated brine, then dried and concentrated. The resulting dark brown solid was purified by sublimation (60°C / 5-6 Torr) to obtain the title compound as colorless crystals (49.07 g, 72%).

[0196]

[0197] 1) Dissolve 96.5mmol of 4,7-dichloro-6-nitro-3-cyanoquinoline and 14.05g (96.5mmol) of 3-chloro-4-fluoroaniline in 900ml of 2-propanol, nitrogen Reflux for 3.5h under protection. TLC (ethyl acetate:n-hexane=1:1) showed no starting point. Stir at room temperature overnight, filter and wash with 2-propanol to obtain 36.5 g of 4-(3-chloro-4-fluoroanilino)-7-chloro-6-nitro-3-cyanoquinoline.

[0198] 2) In 4-(3-chloro-4-fluoroanilino)-7-chloro-6-nitro-3-cyanoquinoline (40.1mmol), 1-(1,1-dimethyl-2- Propyl)-4-methylpiperazine (4a) (10.0g, 60.1mmol), copper (I) iodide (380mg) and tetrakis (triphenylphosphine) palladium (1.39g) in DMF solution (70mL) After blowing nitrogen gas at 50°C for 15 minutes, triethylamine (13.9 mL, 100.0 mmol) was added, and stirred at an oil bath temperature of 140°C for 50 minutes. After standing to cool, the reaction solution was concentrated, and aqueous sodium bicarbonate solution (300 mL) was added. The resultant was extracted with...

Abstract

The invention relates to a quinoline shown in the general formula (I) or a salt accepted in pharmacy, hydrate or solvate, an optical active body or racemate or diastereoisomer mixture thereof, having excellent proteinkinase suppressive activity of tyrosine specificity. The quinoline and the pharmaceutical composition are effective for treating / preventing various cancers, diseases based on arteriosclerosis or chronic eczema.

Description

technical field [0001] The present invention relates to a novel quinoline derivative. More specifically, the present invention relates to quinoline derivatives having tyrosine-specific protein kinase (hereinafter referred to as tyrosine kinase) inhibitory activity. In addition, the present invention relates to a pharmaceutical composition containing the quinoline derivative and a pharmaceutically acceptable carrier, a tyrosine kinase inhibitor containing the quinoline derivative, and an anticancer agent, for diseases and interventions based on arteriosclerosis A therapeutic and / or preventive drug for diseases caused by hyperactivation of tyrosine kinases such as ringworm. Background technique [0002] In cancer chemotherapy, drugs that inhibit DNA synthesis or directly inhibit cell division are often used. However, these drugs currently act as cytotoxicity, and although they are effective against rapidly dividing cancer cells, in many cases, their cytotoxicity is not limit...
