실험 절차
Prepared according to the method described in example 36b) from 3-fluoro-4-methoxybiphenyl (0.99 g), boron tribromide (1.0 M in dichloromethane, 9.8 ml) and dichloromethane (15 ml). After work up the residue was purified by column chromatography over silica eluting with dichloromethane:ethanol (19:1) to give the sub-title compound as a pale yellow crystalline solid (0.52 g).
