Versuchsvorschrift
This is isolated as a minor by product in the synthesis of N-[5-(3-Fluoro-4-methanesulfonyl-phenyl)-4-methyl-thiazol-2-yl]-acetamide (Example 64) when excess methane sulfinic acid sodium salt is added in the first step of the synthesis (64a). The resulting aldehyde is converted into the title compound by the procedure described in parts 64b-d.
