반응 단계
Dihydro-2H-pyran-3(4H)-one (100 mg, 1.00 mmol), tert-butyl carbazate (145 mg, 1.10 mmol, 1.1 equiv) and acetic acid (0.280 mL, 4.99 mmol, 5 equiv) were combined in 1,2-dichloroethane (3 mL), stirred at ambient temperature for 10 minutes and treated with sodium triacetoxyborohydride (296 mg, 1.34 mmol, 1.4 equiv). After stirring for 1 hour, the mixture was poured into water and extracted with ethyl acetate (3×50 mL). The combined organic extracts were dried with sodium sulfate, filtered and concentrated in vacuo to provide the titled compound.
