Reaction Steps
To DMF (40 mL) was added potassium carbonate (9.1 g, 65.9 mmol) and methyl 3-hydroxy-4-methoxybenzoate (10.0 g, 54.9 mmol) and the mixture stirred 30 minutes at room temperature 1-bromo-2-chloroethane (11.0 g, 76.8 mmol) was added and the mixture was heated at 60° C. overnight at which point excess 1-bromo-2-chloroethane (5.5 g, 38.4 mmol) was added and heating continued for 8 hours. After cooling to room temperature, the mixture was diluted with H2O, filtered, and the solid washed with EtOAc to give methyl 3-(2-chloroethoxy)-4-methoxybenzoate (4.04 g, 16.6 mmol, 30%). 1H NMR (300 MHz, DMSO-d6) δ 7.63 (d, 1H), 7.47 (s, 1H), 7.11 (d, 1H), 4.29 (t, 2H), 3.95 (t, 2H), 3.86 (s, 3H), 3.81 (s, 3H); LC-MS (ESI) m/z 245 (M+H)+.
