Reaction Steps

To a stirred solution of methyl 5-hydroxy-2-methyl-3-nitrobenzoate (1.5 g, 7.1 mmol) in ACN (15 mL), were added cesium carbonate (4.6 g, 14 mmol) and 2-bromoethanol (2.5 mL, 35 mmol). The resulting reaction mixture was heated at 80° C. overnight. On completion, the reaction mixture was diluted with water and extraction was carried out using ethyl acetate. The combined organic layers were washed with water, dried and concentrated under reduced pressure. The crude material was purified by silica gel column chromatography to afford the title compound (1.35 g, 74%).
