Reaction Steps
The mixture of 2-(4-nitro-phenyl)-oxirane (24.1 g, 0.15 mol) in ethanolamine (500 mL) was stirred at 40° C. for 2 h, then room temperature for 18 h. The reaction was partitioned between ethyl acetate (200 mL) and water (200 mL) and the aqueous layer was extracted with ethyl acetate (4×100 mL). The combined organic layers were dried over sodium sulfate, filtered and evaporated. The residue was triturated with acetonitrile and collected to give the title compound (19.80 g, 0.09 mmol, 60%) as a white solid. ESMS m/z 227 (M+H)+;
