Versuchsvorschrift

To a suspension of lithium-aluminiumhydride (180 mg, 4.79 mmol) in THF (5 ml, dried Al2O3) at −5-0° C. a solution of N-[5-(4-isopropyl-benzenesulfonylamino)-1H-benzoimidazol-2-ylmethyl]-propionamide (320 mg, 0.80 mmol) in THF (5 ml) was added. After complete addition the mixture was allowed to warm to room temperature and was heated to reflux for 2 h. At 0° C. THF and then water were added. The mixture was dried with Na2SO4. The filtered solution was evaporated in vacuo and the residue was purified by preparative HPLC (water/5% acetonitrile/0.1% acetic acid) to give the product as a yellow oil (10 mg, 3%).
