Abstract
PURPOSE: To prepare the title compound useful as an intermediate of dyes, by reacting aniline or α-naphthylamine with chlorosulfuric acid in a specific organic solvent at a low temperature, precipitating the chlorosulfate of said amine from the solution, and washing the precipitate.
CONSTITUTION: The title compound is prepared in high purity, stability and yield, by (1) reacting aniline or α-naphthylamine with chlorosulfuric acid in an inert organic solvent such as dehydrated chloroform, at ≤0°C, pref. under the steam of dried air or nitrogen gas, (2) precipitating the chlorosulfuric acid salt of said amine at 0W5°C, and (3) washing the salt with an inert organic solvent such as dehydrated chloroform. The weight ratio of the washing solvent to the produced crystal is pref. 2W4 to 1.
