Procedure
2-(Methylthio)-1,3-thiazole-4-carboxylic acid (Intermediate 11; 1.0 g) in thionyl chloride (10 ml) was heated to reflux for 30 min. The solution was cooled to room temperature and concentrated in vacuo. The residue was washed with anhydrous THF and concentrated to yield a black solid which was dried and stored cold under nitrogen (1.2 g). NMR (CDCl3): 2.76 (s, 3H), 8.32 (s, 1H).
