The procedure is as for Example 85, but 4 g (11.1 mmol) of N-(2,6-difluorobenzoyl)-3-amino-3-(3-trifluoromethylphenyl)-1-propanol are employed instead of N-(2,6-difluorobenzoyl)-3-amino-3-(4-chlorophenyl)-1-propanol. 2.7 g (71.1%) of 2-(2,6-difluorophenyl)-4-(3-trifluoromethylphenyl)-5,6-dihydro(4H)1,3-oxazine are obtained as a colorless oil.
