Procedure
A mixture of 4-(4-bromobutoxy)-1,2-dichlorobenzene (0.03 mol), methylamine (20 g) and calciumoxide (7 g) in THF (100 ml) was stirred at 125° C. overnight in an autoclave. The mixture was filtered over dicalite and the filtrate was evaporated. The residue was taken up in DIPE and the mixture was filtered over dicalite. The filtrate was converted into the hydrochloric acid salt (1:1) with HCl/2-propanol. The precipitate was filtered off and dried, yielding 6 g (70.3%) of 4-(3,4-dichlorophenoxy)-N-methyl-1-butanamine (intermediate 4, mp. 132° C.).
