実験手順

In like manner, each of 2-(2-chloro-4-trifluoromethylphenyl)-3-methylbutyramide and 3-(1,2-dibromo-2,2-dichloroethyl)-2,2-dimethylcyclopropaneamide is reacted with trimethyloxonium tetrafluoroborate, giving methyl 2-(2-chloro-4-trifluoromethylphenyl)-3-methylbutanimidate and methyl 2-(1,2-dibromo-2,2-dichloroethyl)-2,2-dimethylcyclopropanimidate, respectively. Each of these imidates is then reacted with 3-phenoxybenzyl alcohol to yield, respectively, 3-phenoxybenzyl 2-(2-chloro-4-trifluoromethylphenyl)-3-methylbutanimidate and 3-phenoxybenzyl 2-(1,2-dibromo-2,2-dichloroethyl)-2,2-dimethylcyclopropanimidate.
