3,3'-Difluoro-4-hydroxy-4'-octyloxybiphenyl → 3,3'-Difluoro-4-octyloxybiphenyl-4'-yl 3-ethylcyclobutanecarboxylate

Participants

Reaction Steps

Except that 0.60 g of 3,3'-difluoro-4-hydroxy-4'-octyloxybiphenyl obtained in Example 5-(c) was used in place of 0.7 g of the crude 3,3'-difluoro-4-hydroxy-4'-decyloxybiphenyl and 0.3 g of 3-ethylcyclobutanecarboxylic acid chloride obtained in Example 13-(d) 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=4/1), the operation was performed in the same manner as in Example 9-(g) to obtain 0.56 g (yield 30.9%) of 3,3'-difluoro-4-octyloxybiphenyl-4'-yl 3-ethylcyclobutanecarboxylate.
