Reaction Steps

1,500 parts of hydrochloric acid (chemically pure) are added to 137.5 parts of tetrahydrofurfurylamine hydrochloride at room temperature. The reaction solution is then heated to 130° C. in a pressure apparatus. This raises the pressure up to 8 bar. After a reaction time of 24 hours, the mixture is cooled to a temperature of 25° C. The dark brown solution is treated with activated carbon and filtered until it is clear, and the mother liquor is concentrated in a rotary evaporator. Recrystallization from 1,200 parts of ethanol gives 130 parts of an analytically pure product, 2,5-dichloropentylamine hydrochloride, having the following formula ##STR35##
