Versuchsvorschrift

An alternate procedure for preparing this benzyl alcohol comprises condensing isophthalaldehyde with 2-methyl-5-fluorobenzothiazole in the presence of acetic anhydride and zinc chloride in hot xylene followed by the reduction of the 3-(5-fluorobenzothiazol-2-yl-trans-ethenyl)benzaldehyde product with sodium borohydride to provide the appropriate benzyl alcohol.
