反応手順
N,N-dichloro-p-toluenesulfonamide (hereinafter abbreviated to "dichloramine T") (7.5 g, 0.032 mol) was dissolved in acetic acid (100 ml), followed by adding to the solution, hydrochloric acid (0.4 ml), dropwise adding to the acetic acid solution of dichloramine T, a solution of 4'-octyloxy-4-biphenycarboxylic acid (20 g, 0.063 mol) dissolved in acetic acid (100 ml), refluxing the mixture, allowing it to stand overnight, distilling off acetic acid and filtering off deposited crystals to obtain 3'-chloro-4'-octyloxy-4-biphenylcarboxylic acid (14.8 g) (C-Sc 146° C., Sc 'N' 224° C. and N'-I 232° C.).
