Versuchsvorschrift
To a stirred solution of 3-phenyl-2-propyne-nitrile (1.27 g, 0.01 mol, Step A) in EtOH (20 mL) was added at RT hydroxylamine hydrochloride (3.5 g, 0.05 mol) followed by 10% NaOH (28 mL). The exothermic reaction was stirred at RT 24 h, then diluted with H2O. The resulting precipitate was filtered off, washed with H2O and dried over P2O5 to afford 3-amino-5-phenylisoxazole as a white crystalline solid.
