The present invention relates to a method for the manufacture of 2-(3-(alkyl or alkenyl)morpholino)-ethan-1-ols by reduction of 8a-(alkyl and alkenyl)hexahydrooxazolo[2,3-c][1,4]oxazines encompassing a process for producing 2-(3-(4-propylheptyl)morpholino)ethan-1-ol with the INN name delmopinol. The invention also relates to 1-chloro-4-propylhept-3-ene, 1-iodo-4-propylhept-3-ene, 8a-(4-5 propylheptyl)hexahydrooxazolo[2,3-c][1,4]oxazine, 8a-(4-propylhept-3-en-1-yl)hexahydrooxazolo[2,3-c][1,4]oxazine and 2-(3-(4-propylhept-3-en-1-yl)morpholino)ethan-1-ol which are intermediates in the delmopinol process.
