Versuchsvorschrift
When using, instead of 4-methoxyphenyl-thiourea of Examples 89 and 90, equivalent amounts of N-phenyl-N'-methyl-thiourea or N-phenyl-N-methyl-thiourea, the other conditions remaining the same, 2-methylamino-benzthiazole (m.p. 137° C.) or 3-methyl-2-imino-benzthiazoline (m.p. 122°) is obtained in an equally good yield and in a high purity.
