Procedure

Dibromoisocyanuric acid (10.6 g) was added at 15° C. to 30° C. to a DMF (90 mL) solution of 4′-fluoro-3-methoxybiphenyl-4-carbaldehyde (16.0 g), and the mixture was stirred for 40 minutes. Then, water (30 mL) was added thereto, and the mixture was further stirred for 1 hour. The deposited solid was collected by filtration and washed with a mixed solution of DMF (15 mL) and water (15 mL) and water (30 mL) in this order to obtain the title compound (20.6 g).
