実験手順

A mixture containing 2-(3-isopropyl-2-oxo-2,3-dihydro-benzoimidazol-1-ylmethyl)-1-(3-methyl-butyl)-1H-benzoimidazole-5-carbonitrile (152 mg, 0.379 mmol), hydroxylamine hydrochloride (95 mg, 1.36 mmole) and potassium carbonate (105 mg, 0.758 mmole) in ethanol (4 mL) and water (2 mL) in a sealed tube was placed in a microwave oven (Smith Creator, Personal Chemistry) and heated at 140° C. for 15 min, followed by 150° C. for 10 min while stirring. The solvents were removed in vacuo and the residue was triturated with water. The white precipitate was collected by filtration, washed with water and dried in vacuo to give N-hydroxy-2-(3-isopropyl-2-oxo-2,3-dihydro-benzoimidazol-1-ylmethyl)-1-(3-methyl-butyl)-1H-benzoimidazole-5-carboxamidine (140 mg, 85%) as a white solid:
