Reaction Steps

To a saturated solution of ethylamine in methanol (40 ml) was added 4-formyl-imidazole-1-sulfonic acid dimethylamide (2.5 g, 12.3 mmol) and the mixture was stirred overnight. Sodium borohydride (0.70 g, 18.5 mmol) was added and the mixture was stirred at room temperature for 3 h. Water was added and the solution was extracted three times with ethyl acetate. The combined organic layers were dried over magnesium sulfate and evaporated. The residue was purified by flash chromatography (SiO2: dichloromethane/methanol=9:1) to yield a light yellow oil (0.785 g, 27%); MS (ISP): 233.1 ((M+H)+.).
