Reaction Steps
A mixture of 2-chloro-1H-benzoimidazole (1 g) in 4 mL of ethane-1,2-diamine was heated to 10° C. for several hours until complete by HPLC. The reaction was allowed to cool and diluted with a mixture of chlororform and isopropanol (3:1). The organic phase was washed with water then dried and concentrated to give 216 mg of product as a solid which was used in the next step without further purification. MS(ES): m/e (EI*) 177.1 [M+H]
