Procedure
In Stage 2, 2-(4′-chlorophenyl)ethyl bromide was reacted with 1-amino-2-propanol to form the secondary amine, 1-[2-(4-chloro-phenyl)-ethylamino]-propan-2-ol. 1-[2-(4-Chloro-phenyl)-ethylamino]-propan-2-ol was separated from excess 1-amino-2-propanol and water soluble byproducts by extraction into toluene and removing water from the toluene containing 1-[2-(4-Chloro-phenyl)-ethylamino]-propan-2-ol by azetropic distillation and can be used directly into the next step without further purification and without isolation.
