実験手順
Methyl 2-amino-3-hydroxybenzoate (0.5 g; 2.99 mmol) was dissolved in m-xylene (40 ml) with warming to 60° C. 4-Nitrobenzoyl chloride (0.556 ml; 2.99 mmol) was added dropwise, and this was left to stir for 4 hours. The solution was cooled to ambient temperature and the m-xylene removed under reduced pressure. The solid was dissolved in water (100 ml) and the organics extracted into ethyl acetate (3×50 ml). The organic fractions were pooled, dried over magnesium sulphate, filtered and the solvent removed under reduced pressure.
