실험 절차
To a solution of tert-butyl 5-(hydroxymethyl)-3,6-dihydro-1(2H)-pyridinecarboxylate (14.65 g, 68.69 mmol) in dichloromethane was added MnO2 (89.58 g, 1030.36 mmol), then stirred overnight at room temperature. The reaction mixture was filtered through Celite®, the filtrate was concentrated under reduced pressure to give tert-butyl 5-formyl-3,6-dihydro-1(2H)-pyridinecarboxylate, which was pure enough to be used for the next reaction. (13.55 g, yield 94%)
