Versuchsvorschrift
2.14 g 2-Amino-5-cyanothiazole was dissolved in 10 ml acetic acid, and 1.8 ml acetic anhydride was added to carry out reaction at 100° C. for 30 min. The reaction product was cooled down, and filtered to obtain 2.5 g of a clay-solid having metallic luster (yield 80%), 1H NMR (DMSO-d6) 2.22 (3H, s), 8.36 (1H, s), 12.95 (1H, s).
