実験手順

A mixture of 2-bromo-4-ethylphenylamine (1.6 g, 8.0 mmol), propane-1,2,3-triol (1.84 g, 2.5 equiv), FeSO4 (0.067 g, 0.30 equiv), 3-nitrobenzenesulfonic acid sodium salt (1.13 g, 0.63 equiv) in 4.5 mL of methanesulfonic acid was heated at 135° C. for 3 hours and then cooled to room temperature. 2 N Aqueous NaOH (˜40 mL) was added and the mixture was extracted with EtOAc (3×50 mL). The organic layer was washed with saturated aqueous NaHCO3 (200 mL) and brine (200 mL), dried over magnesium sulfate and concentrated. The residue was purified by silica gel flash column chromatography using 5% to 20% EtOAc in hexane to afford the title compound as a black solid (1.3 g). MS (ES) m/z 235.9 (M+H+).
