Versuchsvorschrift

Dimethylsulfate (10.3 mL, 109 mmol) was added to a mixture of 3-bromo-[1,1′-biphenyl]-4-ol and sodium hydroxide (8 g, 201 mmol) in water (12.4 mL) at 0° C. After stirring for 2 hours at reflux, ammonia (1.2 mL) was added to the mixture. The solid was filtered and washed with water. The product, 3-bromo-4-methoxy-1,1′-biphenyl, was crystallized from heptane.
