3-Nitro-5-(1,2-dihydroxyethyl)benzoic acid methyl ester (0.40 g, 1.69 mmol) and 2,3-dihydroxypropylamine (0.17 g, 1.86 mmol) were dissolved in methanol (2 ml) and the solution was stirred at 75° C. for 1 h. The pressure was then reduced to 200 mm Hg and stirring was continued at 95° C. for 2 h. The crude reaction mixture was purified by preparative HPLC. Yield: 0.40 g (78%).
