In a similar way, substituting trans-10-fluoro-3,4,4a,5,6,11b-hexahydro-2H-[1]benzoxepino[5,4-b]-1,4-oxazine for the trans-3,4,4a,5,6,11b-hexahydro-2H-[1]benzoxepino[5,4-b]-1,4-oxazine above and using hydrogen chloride instead of maleic acid, results in the formation of trans-10-fluoro-3,4,4a,5,6,11b-hexahydro-4-methyl-2H-[1]benzoxepino[5,4-b]-1,4-oxazine hydrochloride having a mp. of 244°-245° C.
