<p>A process for the production of a phenol derivative of the formula (2), which comprises subjecting a diester compound of the formula (1) in which a hydroxyl group is protected by an acyl group, to a reaction for removal of protection, wherein the reaction is carried out in the presence of an aliphatic amine as a protection-removal agent, <CHEM> <CHEM> wherein X is hydrogen or fluorines Y is -CH3 or -CF3, Q is an alkyl group having 1 to 4 carbon atoms, p is 0 or 1, m is an integer of 2 to 7, n is an integer of at least 1, and C* is an asymmetric carbon, the process enabling to obtain the phenol derivative of the formula (2) useful as an intermediate for a liquid crystal compound with ease and at high purity.</p> |
