Versuchsvorschrift
A solution of 4-benzoyl phenyl boronic acid (226.00 mg, 1.00 mmol) and hydroxylamine hydrochloride (84.00 mg, 1.20 mmol) in pyridine (5 mL) and EtOH (5 mL) was refluxed at 125° C. for 24 h. Reaction was then concentrated in vacuo to give a crude product which was used for next step without further purification. MS (ES+): m/z 241.89 (100)[MH+]. HPLC: tR=2.56 min (Open Lynx polar—5 min).
