1-(2-BENZOTHIAZOLYL)-4-BROMOBENZENE synthesis
- Product Name:1-(2-BENZOTHIAZOLYL)-4-BROMOBENZENE
- CAS Number:19654-19-4
- Molecular formula:C13H8BrNS
- Molecular Weight:290.18
Yield:19654-19-4 97%
Reaction Conditions:
with potassium tert-butylate in toluene at 20 - 110; for 48 h;
Steps:
8 A method for preparing 2-(4-bromophenyl)benzo[d]thiazole includes the following experimental steps:
At room temperature, add o-aminothiophenol 1a (0.6 mmol), toluene solvent and 4-bromobenzyl alcohol 2b (0.2 mmol) to the reactor in sequence, stir at room temperature to fully dissolve them, and add to the preparation of Example 1 in sequence The obtained HKUST-1-400 catalyst (20mg), potassium tert-butoxide (0.2mmol), after dissolving, continue the reaction and place it at 110°C for 2 days. After the completion of the reaction is detected by TLC, the Cu-MOF derivative HKUST is filtered out first -1-400 catalyst and then column chromatography to obtain the target compound 3b with a yield of 97%.
