Versuchsvorschrift
A mixture of N-triphenylmethyl-4-(trans-2-cyano-cyclopropyl)imidazole (200 mg, 0.54 mmol) and trifluoroacetic acid (TFA) (10 mL) was stirred at room temperature for 1-3 hours. The TFA was evaporated under reduced pressure. The resulting mixture was diluted with distilled water (5 mL) and extracted with ether (3×15 mL). The aqueous layer was lyophilized to give the product as a solid (73 mg, 55% yield).
