실험 절차

One example of a way of carrying out this Step is by a standard method using sodium hydroxide to hydrolyse commercially available 4'-bromo-4-benzene-sulphonyloxybiphenyl in a mixture of water and dioxan as solvent. The colourless crystals obtained by crystallisation of the product from ethanol have a melting point of 166° C.
