Reaktionsschritte
A mixture of 3-methoxy-benzene-1,2-diol (1.161 g, 8.28 mmol) in DMF (10 mL) was added to bromo-chloro-methane (611 ul, 1.1 equivalents) and stirred at 90 degrees Celsius for 4 hours. The mixture was poured into water and extracted with dichloromethane. The organic layer was poured thru a phase separator cartridge and concentrated to dryness. The crude product is a yellow liquid. The liquid was purified by column chromatography yielding 1.21 g, (96%). 1H-NMR (DMSO, 500 MHz) 6.7 (t, 1H), 6.63 (d, 1H), 6.58 (d, 1H), 5.97 (s, 2H), 3.83 (s, 3H) HPLC (method A) 2.86 min.
