Versuchsvorschrift

Cold (0° C.) 4 NHCl in dioxanes (4 mL) was added via syringe to (S)-2-{5-[2-(4-{2-[(S)-1-((R)-2-methoxycarbonylamino-2-phenyl-acetyl)-pyrrolidin-2-yl]-3H-imidazol-4-yl}-phenyl)-pyrimidin-5-yl]-1H-imidazol-2-yl}-pyrrolidine-1-carboxylic acid tert-butyl ester (104.6 mg, 0.146 mmol) in a 100 mL pear-shaped flask followed by MeOH (0.5 mL). The homogeneous mixture was stirred at room temperature for 15 min before a precipitate was observed. After stirring further for 1.75 h, the suspension was diluted with ether and hexanes. Suction-filtration of a small portion of the suspension yielded the title compound as a yellow solid which was used for characterization purposes. The balance of the suspension was concentrated down to dryness and placed under high vacuum for 16 h. There was isolated the rest of the title compound also as a yellow solid (137.7 mg, 123%) which was used without further purification.
