Participants

Reaction Steps

To a solution of 2-amino-1-(4-nitrophenyl)ethanone (500 mg, 2.30 mmol), paraformaldehyde (207 mg, 6.90 mmol), and sodium cyanoborohydride (433 mg, 6.90 mmol) in methanol (30 mL) was added acetic acid (catalytic) and the reaction stirred at room temperature for 18 h. The reaction mixture was quenched with water and the layers were separated. The combined organic layers were dried over anhydrous sodium sulfate, filtered, concentrated, and chromatographed (CH2Cl2/MeOH) to afford the desired product (164 mg, 34%) as an orange oil: ESI MS m/z 211 [C10H14N2O3+H]+.
