Into a reaction vial were placed 10 mg of cyclobutylamine, 20 mg of HOAt, 53 mg of (S)-2-{[1-(1-Ethyl-propyl)-2-thiophen-2-ylmethyl-1H-benzoimidazole-5-carbonyl]-amino}-4-methyl-pentanoic acid. Then 0.11 ml DIPEA in 1 ml DMF were added, followed by 67 mg PyBrOP in 0.5 ml DMF. The reaction was shaken at RT over night, then filtered and purified by HPLC to yield 39 mg (74%) of 1-(1-ethyl-propyl)-2-thiophen-2-ylmethyl-1H-benzoimidazole-5-carboxylic acid ((S)-1-cyclobutylcarbamoyl-3-methyl-butyl)-amide.
