Reaction Steps

To a round bottom flask was added 2-pyrazinecarboxaldehyde (770 mg, 7.12 mmol) in 10 mL of nitromethane, followed by the addition of triethylamine (721 mg, 7.12 mmol). The reaction mixture was stirred at room temperature for 1 h. The reaction mixture was concentrated in vacuo. The residue was loaded onto a flash chromatography column. The column was eluted with 0–5% MeOH/CH2Cl2. The product fractions were collected and concentrated to afford 1124 mg (93.3%) of 2-nitro-1-pyrazin-2-yl-ethanol. (TLC: Rf=0.2, 5% MeOH/CH2Cl2, UV).
