37924-85-9, Rate laws may be derived directly from the chemical equations for elementary reactions. This is not the case, however, for ordinary chemical reactions.3-(Bromomethyl)benzo[d]isoxazole, cas is 37924-85-9,the Benzisoxazole compound, below Introduce a new synthetic route.
3-Bromomethyl-benzo[d]isoxazole-5-sulfonyl chloride Chlorosulfonic acid (1.5 ml, 22 mmol) was slowly added to 3-Bromomethyl-benzo[d]isoxazole (1.0 g, 4.7 mmol) at RT under argon. The reaction was heated at 90 C. for 12 h and then left at RT for 6 h. The resulting viscous oil was quenched over ice, extracted with EtOAc, dried over MgSO4 and concentrated in vacuo to a brown oil (1.17 g, 80% yield).; 3-Bromomethyl-benzo[d]isoxazole-5-sulfonyl chloride Chlorosulfonic acid (1.5 ml, 22 mmol) was slowly added to 3-Bromomethyl-benzo[d]isoxazole (1.0 g, 4.7 mmol) at RT under argon.

After reaction of this material with the core the aliphatic bromine may be displaced by an appropriate nucleophile.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 37924-85-9.
