Versuchsvorschrift

A mixture of 5-(bromomethyl)-4-methyl-2-[4-(trifluoromethyl)phenyl]-1,3-thiazole (intermediate 3, 1.48 g) and triethylphosphite (1.5 ml) was heated under nitrogen at 150° C. for 1 hour. The mixture was allowed to cool and excess triethylphosphite was removed under reduced pressure. This gave the title compound as a yellow solid.
