Process for producing tert-butyl 4'-methyl-2-biphenylcarboxylate

摘要

A process for preparing tert-butyl 4'-methyl-2-biphenylcarboxylate characterized in that 4'-methyl-2-biphenylcarboxylic acid is reacted with isobutene in the presence of an acid catalyst. According to the present invention, tert-butyl 4'-methyl-2-biphenylcarboxylate having high quality can be conveniently and industrially advantageously prepared in a high yield under mild reaction conditions such as ambient temperatures without complicated procedures or any hazardous solvents.
