Reaction Steps
A 50 mL round bottom flask was charged with 1 (680 mg, 2.5 mmol), hydroxylamine HCl (191 mg, 2.75 mmol), pyridine (0.25 mL, 3.0 mmol) and ethanol (10 mL). The resulting reaction mixture was stirred at rt overnight. The crude product was concentrated, absorbed onto silica gel, and purified by flash chromatography (97:3 CH2Cl2/MeOH to give 2 as an orange solid. LCMS m/z 289.2 (MH+), tR=2.06 min.
