반응 단계
5 cm3 of acetic anhydride are added dropwise to 7 cm3 of pyridine at 20° C. After 5 min, 1 g of 2-amino-6-thiocyanatobenzothiazole (commercial) is added. The yellow suspension is stirred for 4 h and then concentrated to dryness under vacuum. The residue is made into a paste in ethyl ether. The insoluble material is isolated by filtration, to give 1.1 g of 2-(acetylamino)-1,3-benzothiazol-6-ylthiocyanate in the form of a yellow solid, the characteristics of which are as follows:
