Pyridine (14 g, 0.18 Mol) and 4-nitrophenylacetic acid (32 g, 0.18 Mol) were stirred in toluene (100 ml) whilst trimethylacetylchloride (21 g, 0.18 Mol) was added. The toluene was evaporated to yield 4-nitrophenylacetic trimethylacetic anhydride. 3-Aminophenol (20 g, 0.18 Mol) was stirred in DMF (100 ml) and treated with the mixed anhydride and pyridine (14 g) in dimethylformamide (DMF) dropwise. The solution was diluted with water and the product isolated by filtration and dried (19 g, 39%).
