Известен способ получени изопропиламинов взаимодействием 1-хлор-З-арилоксипропанола-2 с изопропиламином, а также фенола с 1-хлор-З-изопропиламинопропанолом-2 . Однако выход целевых продуктов по этому способу не превышает 30%.A known method for producing isopropylamines by reacting 1-chloro-3-aryloxypropanol-2 with isopropylamine, as well as phenol with 1-chloro-3-isopropylaminopropanol-2. However, the yield of the target products by this method does not exceed 30%.
