Ethyl bromoacetate → HCID 22050564, compound

Participants

Reaction Steps

To a solution of 5-fluoro-2-methylphenol (1.00 g, 7.93 mmol) and ethylbromoacetate (1.59 g, 9.51 mmol) in DMF (15 mL) was added K2CO3 (1.10 g, 7.93 mmol). After 30 min at RT, DMF was removed by distillation. The crude product was washed with 5% citric acid (30 mL) and water (30 mL), extracted in DCM (3×20 mL), dried over Na2SO4, filtered, concentrated, and dried in vacuo. Desired product obtained as yellow oil (1.30 g, 77%). 1H NMR (CD3OD/400 MHz) δ 7.09 (t, 1H, J=8.8 Hz), 6.58 (m, 1H), 6.56 (m, 1H), 4.71 (s, 2H), 4.23 (q, 2H, J=7.2 Hz), 2.18 (s, 3H), 1.27 (t, 3H, J=7.2 Hz). ES HRMS m/z 212.0847 (M+H calculated for C11H13FO3 requires 212.0849). Step 2: Preparation of ethyl [2-(bromomethyl)-5-fluorophenoxy]acetate.
