Versuchsvorschrift

5-(Benzoxazol-2-yl)-1-(2-(tert-butoxycarbonylamino)ethyl)-2-methylbenzimidazole (see Working Example 55-2) (100 mg, 0.255 mmol) was added to a 4N hydrochloric acid solution in dioxane (10 mL), and this was heated to reflux for 5 hours. After the reaction was complete, this was concentrated to dryness to yield the title compound (95 mg, quant.) as white crystals.
