Reaction Steps

To a solution of 2-chloro-5-methylphenol (10.7 g, 75 mmol) in DMF (40 mL) was added potassium carbonate (26 g, 188 mmol) followed by neat methyl iodide (4.9 mL, 79 mmol). The reaction mixture was stirred at room temp for 6 hr, extracted with EtOAc, washed with water and brine, dried and concentrated in vacuo to give 4-chloro-3-methoxytoluene (10.8 g, 92%). 1H-NMR (DMSO-d6): δ 2.26 (s, 3H), 3.79 (s, 3H), 6.71-6.73 (dd, 1H), 6.94 (s, 1H), 7.22-7.24 (d, 1H).
