2-Butyl-4-chloro-5-formylimidazole Usage
2-Butyl-4-chloro-5-formylimidazole can be used as an antihypertensive drug for losartan.
There are four main synthetic routes for imidazolaldehyde
1. Route one uses valeronitrile as the raw material, and the target compound is obtained through addition, condensation, chlorination and oxidation;
2. Route 2 uses valeronitrile as the raw material, and the target compound is obtained by addition, substitution, cyclization, chlorination, and oxidation;
3. Route three uses valeronitrile as the raw material, and the target compound is obtained by addition, substitution, cyclization, and chlorination;
4. Route 4 takes 2-n-butyl-4-chloro-5-hydroxymethyl-imidazole as the raw material and obtains the target compound through oxidation
