Versuchsvorschrift
Add the amino-alcohol from step A (2.2 g) to a mixture of methanesulfonic acid (100 mL) and dichloromethane (150 mL) and stir overnight at room temperature. Pour the mixture into ice-water, separate and concentrate the organic layer to a residue. Triturate with benzene then recrystallize from ethanol to give 8.7 g of the title amine as the methanesulfonate salt, mp=198°-199° C.
