Second, the Synthetic Route we will recommend is the most important for your reference?

First, synthesis line of 5-bromodihydroindole CAS NO. 22190-33-6  as follows

The synthesis route can involve multiple steps. The following is a possible synthesis route, but please note that the specific synthesis method may vary depending on laboratory conditions and required purity:

A method for synthesizing 5-bromodihydroindole involves starting from N-formylindoline, followed by bromination reaction and subsequent hydrolysis step 1. The specific steps are as follows:

Dissolve N-formylindoline in a suitable solvent (such as dichloromethane). ‌

Add dibromohydantoin to the solution and react at low temperature (such as -10~0 ° C) until the raw material disappears. ‌

The reaction mixture is washed with sodium bisulfite aqueous solution, washed with water, concentrated and crystallized, and dried to obtain brominated intermediate products. ‌

Dissolve the brominated intermediate obtained in the previous step in methanol, add potassium hydroxide aqueous solution, and heat the reaction until the raw material disappears. ‌

The reaction mixture was quenched with water, concentrated, extracted with dichloromethane, crystallized and dried to obtain 5-bromodihydroindole. ‌

Please note that the above synthesis route is only an example and may need to be adjusted according to specific laboratory conditions. In addition, due to the complex reaction conditions and potential hazards involved in chemical synthesis, safety operating procedures should be strictly followed in practical operations and carried out under the guidance of professional personnel. ‌
