Sodium hydride → HCID 86589696, compound

Participants

Reaction Steps

Under nitrogen, to a suspension of sodium hydride (60% in oil, 189 mg) in N,N-dimethylformamide (20 ml) was dropwise added 2-benzyloxycarbonylamino-5-hydroxypyridine (1.1 g) in N,N-dimethylformamide (12 ml) at 5° C., and the mixture was stirred at room temperature for 1 hour. To this one was added (2S)-(+)-1-tosyloxy-2,3-epoxypropane (1.1 g) at 5° C., and the mixture was stirred at room temperature for 7 hours. The resulting mixture was poured into saturated aqueous sodium hydrogencarbonate and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous magnesium sulfate and evaporated in vacuo. The residue was purified by column chromatography on silica gel (chloroform:ethyl acetate=9:1) to give 2-benzyloxycarbonylamino-5-[(2S)-oxiranylmethoxy]pyridine (780 mg).
