実験手順

218 mg of 1-(1-ethyl-propyl)-2-thiophen-2-ylmethyl-1H-benzoimidazole-5-carboxylic acid ((S)-1-cyanomethyl-3-methyl-butyl)-amide and 124 mg of azidotrimethyltin in 10 ml of dry toluene were heated under Argon for 48 h. The precipitated crude product was isolated by suction and then dissolved in 10% aqueous sodium bicarbonate solution and filtered with addition of charcoal. The pH of the filtrated was adjusted to 5, and the precipitated product was isolated by suction, washed with water and dried in vacuo to obtain 100 mg (42%) of 1-(1-Ethyl-propyl)-2-thiophen-2-ylmethyl-1H-benzoimidazole-5-carboxylic acid [(S)-3-methyl-1-(1H-tetrazol-5-ylmethyl)-butyl]-amide.
