실험 절차

To a solution of 3-nitrophenol (10 g, 71.9 mmol) in DMF (40 ml) was added NaOH pellets (3.16 g, 79.1 mmol) and 2-bromoethanol (5.6 ml, 79.1 mmol). The reaction mixture was heated at 60° C. for 18 h. LCMS indicated 65% conversion to the required product. The reaction mixture was diluted with water (10 ml) and was slowly neutralised with 2M HCl. The reaction mixture was extracted with EtOAc (50 ml) and washed with water (50 ml). The EtOAc layer dried (Na2SO4), filtered and evaporated to dryness. Flash column chromatography purification eluting with 30% EtOAc/heptane gave the required product (8.2 g, 62% yield). LCMS purity 100%, m/z 184 [M+H]+.
