Reaction Steps

To a solution of N-(5-acetylpyrazin-2-yl)-2,2-dimethylpropanamide (500 mg) in ethanol (10 mL) and THF (10 mL) was added sodium borohydride (86 mg) under ice-cooling, followed by stirring for 30 minutes under ice-cooling. To the reaction mixture was added 1 M hydrochloric acid under ice-cooling, followed by extraction with ethyl acetate. The organic layer was washed with saturated aqueous sodium bicarbonate and saturated brine, dried over anhydrous magnesium sulfate, and then concentrated to obtain N-[5-(1-hydroxyethyl)pyrazin-2-yl]-2,2-dimethylpropanamide (525 mg) as a brown solid.
