Reaction Steps

For example, 4'-alkoxy-4-bromobiphenyl (17) is reacted with triphenylphosphin to obtain triphenylphosphonium salt of 4'-alkoxybiphenyl (21). The thus obtained triphenylphosphonium salt of 4'-alkoxybiphenyl (21) is reacted with 6-formyl-2-naphthalenecarboxylic acid methyl ester as a solution in such as methylene chloride and then the resulting compound is reacted with hydrogen in the presence of the reducing catalyst such as paradium carbon in a solvent such as tetrahydrofuran (THF) to obtain 6-[4'-alkoxy-4-biphenyl)ethyl]-2-naphthalenecarboxylic acid methyl ester. The resulting 6-[4'-alkoxy-4-biphenyl)ethyl]-2-naphthalenecarboxylic acid methyl ester is hydrolysised to obtain 6-[4'-alkoxy-4-biphenyl)ethyl]-2-naphthalenecarboxylic acid (22).
