Abstract
PURPOSE: The reaction of a specific trithiocyclopropenium salt with o-aminothiophenol is conducted to produce title compound useful as agricultural chemical, drug and starting compound of various kinds of syntheses utilizing the reactivity in high yield with no side reaction.
CONSTITUTION: Trithiocyclopropenium salt of formula I (R1 is lower alkyl; X- is anion) and o-aminothiophenol of formula II (Y is H, nonprotonic substituent) are made to react in a solvent as methylene chloride or chloroform at 0W100°C, usually room temperature to give the benzothiazole derivative of formula III. The compund of formula I is, e.g., triethylcyclopropenium perchlorate and the compound of formula II is, e.g., o-aminothiophenol. A base may be added to the reaction system and a preferable example is potassium t-butoxide.
