Following the same procedure with the same molar proportion of materials as in Production Example 1, 2-(2,6-difluorophenyl)-4-{[2,3-dimethyl-4-(2-ethoxyethyl)phenoxy]methyl}-2-oxazoline (Compound No. 2) is obtained by using 2-amino-3-[2,3-dimethyl-4-(2ethoxyethyl)phenoxy]propanol instead of 2-amino-3-[4-(1,1-dimethylethyl)phenoxy]propanol. In the same way, 2-(2,6-difluorophenyl)-4-[(4-benzyl-2,3-dimethylphenoxy) methyl]-2-oxazoline (Compound No. 49), 2-(2,6-difluorophenyl)-4-{[4-(2-ethoxyethyl)-2-methylphenoxy]methyl}-2-oxazoline (Compound No. 50) or 2-(2,6-difluorophenyl)-4-{(4-benzyl-2-methylphenoxy)methyl}-2-oxazoline (Compound No. 51) is obtained by using 2-amino-3-(4-benzyl-2,3-dimethylphenoxy)propanol, 2-amino-3-[4-(2-ethoxyethyl)-2-methylphenoxy]propanol or 2-amino-3-[4-benzyl-2-methylphenoxy)propanol, respectively.
