STR64 A compound of 3-(chloromethyl)-isoxazole (1.2 g) was added dropwise at a temperature of 20 to 30 C. under stirring to a mixture of 7-fluoro-6-(4,5,6,7-tetrahydro-2H-isoindole-1,3-dion-2-yl)-2H-1,4-benzoxazin-3(4H)-one (3.16 g), acetonitrile (50 ml) and potassium carbonate (1.5 g). The reaction mixture was heated under refluxing for 3 hours, cooled to room temperature, and filtered. The filtrate was concentrated under a reduced pressure to dryness. The resultant residue was mixed with toluene (150 ml) to form a suspension, which was then filtered to remove the undissolved materials therefrom. The filtrate was concentrated under a reduced pressure so as to obtain a viscous material, which was thereafter dissolved in a minimum amount of ethanol. The ethanol solution was cooled to precipitate a crystalline product. This product was separated by filtration and dried, so that the aimed compound, i.e. 7-fluoro-4-(isoxazol-3-ylmethyl)-6-(4,5,6,7-tetrahydro-2H-isoindole-1,3-dion-2-yl)-2H-1,4-benzoxazin-3(4H)-one (3.3 g) was obtained. m.p. 206-210 C.
57684-71-6 3-(Chloromethyl)isoxazole 4913025, aIsoxazoles compound, is more and more widely used in various fields.
