反応手順
The 2-[(cyclopropylcarbonyl)amino]-1,3-benzothiazol-6-yl thiocyanate was prepared in a manner similar to the method described in Example 18b, but using 2 g of commercial 2-amino-6-thiocyanatobenzothiazole and 1.21 g of cyclopropanecarboxylic acid chloride in 20 cm3 of pyridine after reaction for 5 h at 20° C. 2.65 g of 2-[(cyclopropylcarbonyl)amino]-1,3-benzothiazol-6-yl thiocyanate are thus obtained in the form of a yellow powder, the characteristics of which are as follows:
