62348-13-4, Isoxazole-5-carbonyl chloride is a Isoxazoles compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
62348-13-4, EXAMPLE 2 6.52 parts of 2-methylpyridine were added to a stirred mixture of 15.7 parts of 7-chloro-5-nitro-8-hydroxyquinoline in 190 parts of 1,2-dichloroethane at 25 C. in the course of 5 minutes, and the mixture was stirred for 5 minutes. 9.2 parts of isoxazole-5-carbonyl chloride were then added at from 20 to 25 C. in the course of 10 minutes, while stirring, and stirring was continued for 3 hours at 55 C. The reaction mixture was evaporated to dryness under reduced pressure, and the residue was stirred in 200 parts of 0.5N hydrochloric acid for 5 minutes. The precipitate was filtered off under suction, washed with water and stirred for 10 minutes in 200 parts of dilute sodium carbonate solution. Filtration under suction, washing with water at 60 C. and drying gave 17.5 parts of 7-chloro-5-nitro-8-(isoxazole-5′-carbonyl)-oxyquinoline of melting point 132-134 C.
As the paragraph descriping shows that 62348-13-4 is playing an increasingly important role.
