Procedure

Except that 0.60 g of the crude 3,3'-difluoro-4-hydroxy-4'-hexyloxybiphenyl obtained in Example 12-(c) was used in place of 0.7 g of the crude 3,3'-difluoro-4-hydroxy-4'-decyloxybiphenyl and 0.4 g of 3-pentylcyclobutanecarboxylic acid chloride obtained in Example 1-(a) in place of 0.5 g of the 3-octylcyclobutanecarboxylic acid chloride used in Example 9-(g) and purification was carried out by way of column chromatography on silica gel (eluent: hexane/benzene=3/1), the operation was performed in the same manner as in Example 9-(g) to obtain 0.55 g (yield 65.5%) of 3,3'-difluoro-4-hexyloxybiphenyl-4'-Yl 3-pentylcyclobutanecarboxylate.
