Reaction Steps
To a stirred mixture of methyl 4-hydroxyphenylacetate (10.0 g) in acetic acid (55 ml) was added nitric acid (22.1 ml) at 0° C. The reaction mixture was stirred at 0° C. for 2 hours. After warmed to 20° C., the reaction mixture was diluted with water (200 ml) and precipitated crystals were collected. The crystals were dissolved in chloroform, and the solution was washed with water, dried over magnesium sulfate and evaporated in vacuo. The residue was recrystallized from a mixture of chloroform and hexane to give methyl 4-hydroxy-3-nitrophenylacetate (9.3 g) as yellow crystals.
