摘要:
An alkyl ester of 4-(5-(bis(2-hydroxyethyl)amino)-1-methyl-1H-benzo[d]imidazol-2-yl)butyric acid, such as ethyl 4-(5-(bis(2-hydroxyethyl)amino)-1-methyl-1H-benzo[d]imidazol-2-yl)butanoate, is obtained by reacting an alkyl ester of 4-(5-amino-1-methyl-1H-benzo[d]imidazol-2-yl)butyric acid with 2-hydroxyacetaldehyde under reducing conditions.
