Zusammenfassung:N-(2-amino-3,5-dibromobenzyl)- N-methyl-cyclohexylamine, the hydrochloride of which has the formula is prepared by brominating 1,4- dihydro-2H-3,1-benzoxazin-2-one with free bromine to form the hitherto unknown intermediate 6,8-dibromo- 1,4-dihydro-2H-3,1-benzoxazin-2- one, and reacting this with N-methyl- cyclohexylamine to bromhexin. Preferably, the reaction takes place by heating in N-monomethylformamide to the boiling point of the latter.
