37924-85-9, An elementary termolecular reaction involves the simultaneous collision of three atoms, molecules, or ions.3-(Bromomethyl)benzo[d]isoxazole, cas is 37924-85-9,the Benzisoxazole compound. Here is a downstream synthesis route of the compound 37924-85-9
(b) Sodium hydride (50% in mineral oil, 3.4 g, 0.071 mole) is washed free of mineral oil with hexane (3*30 mL) and suspended in dimethylformamide (100 mL). This suspension is well stirred and maintained near room temperature (water bath) during the dropwise addition of a solution of imidazole (4.8 g, 0.071 mole) in dimethylformamide (25 mL). The reaction mixture is stirred at room temperature for 1 hour when 3-bromomethyl-1,2-benzisoxazole (15.0 g, 0.071 mole) is added all at once. The mixture is then heated at 85 C. for 8 hours. The solvent is evaporated in vacuo and the residue is taken up in methylene chloride (200 mL) and washed with water (3*50 mL). The organic solution is dried over anhydrous sodium sulfate, filtered and evaporated to give 3-[(1H-imidazol-1-yl)methyl]-1,2-benzisoxazole, which is purified by recrystallisation from isopropanol, m.p. 52-55 C.
