실험 절차
To a solution of 2-benzhydryl-3-(4-methoxyphenyl)-1,2-oxaziridine 40 (3.52 g, 11.1 mmol) in methanol (100 mL) was added hydroxylamine-HCl (2.31 g, 33.3 mmol) and stirred at room temperature. for 16 h. The reaction mixture was concentrated under vacuum and diluted with aqueous NaOH solution (to pH=13), followed by extraction with ethyl acetate. The combined organic layers were dried over anhydrous Na2SO4, filtered, and concentrated. The crude material was concentrated and purified by silica gel column chromatography with gradient of ethyl acetate (10-50%) in hexane to afford compound 41 as a light yellow solid (450 mg, 20%). LRMS (ESI): (calc.) 199.3 (found) 167.2 (M-NHOH)+.
