実験手順
A solution of (4-ethyl-3-methoxy-phenyl)-[7′-(hydroxymethyl)spiro[piperidine-4,4′-pyrrolo[2,1-c][1,4]benzoxazine]-1-yl]methanone (270 mg, 0.62 mmol) and manganese dioxide (270 mg, 3.1 mmol) in dichloromethane (5 mL) was stirred at 60° C. overnight. The reaction was filtered, evaporated and submitted to the next step without further purification. ESI-MS m/z calc. 430.5, found 431.7 (M+1)+; Retention time: 2.01 minutes (3 min run).
