Isoamyl Nitrite → HCID 69527459, compound

Participants

Reaction Steps

To a refluxing solution of isoamyl nitrite (1.5 mL) in tetrahydrofuran (4.6 mL) was added a solution of ethyl 5-amino-1-[(1R,2S)-2-hydroxy-1-(hydroxymethyl)propyl]-1H-imidazole-4-carboxylate (0.92 g) in tetrahydrofuran (23 mL) dropwise over 45 minutes, and the mixture was refluxed for 75 minutes. The reaction mixture was cooled to ambient temperature and concentrated in vacuo. The residue was purified by column chromatography on silica gel (gradient elution; 10:1 to 5:1 chloroform-1% ammonium hydroxide/methanol) to give ethyl 1-[(1R,2S)-2-hydroxy-1-(hydroxymethyl)propyl]-1H-imidazole-4-carboxylate (0.50 g).
