실험 절차

2 g (12.1 mmol) of 2-hydrazino-1,3-benzothiazole and 1.58 g (12.1 mmol) of acetoacetic ester are stirred in 40 ml of glacial acetic acid for 2 hours at 90° C. The mixture is then diluted with water and the precipitated crystals are filtered off with suction, washed again with water and dried under reduced pressure.
