実験手順

3-chloro-1,2-di-(hydroxymethyl) benzene was prepared in 97% yield via borane reduction of 3-Chlorophthalic acid in a manner similar to that was used for the preparation of 3-fluoro-1,2-di-(hydroxymethyl) benzene as described in Example 13, Step A. 3-Chlorophthalic acid was prepared from according to the literature procedure of Fertel, L. B. et al. J. Org. Chem. 1993, 58(1), 261-263.
