Versuchsvorschrift
A solution of o-toluoyl chloride (17 g) in a few milliliters of pyridine was added dropwise to a suspension of 2-amino-5-nitrothiazole (16 g) in pyridine (100 ml), initially at room temperature, then at 0°. After the addition was complete, the reaction mixture was stirred for 2 hr at room temperature, and was then quenched in ice-water. Recrystallisation of the precipitated amide from 2-methoxyethanol afforded 2-methyl-N-(5-nitro-2-thiazolyl)benzamide, m.pt. 228°-230°.
