実験手順
Methyl 2-(2,2,2-trifluoroethoxy)benzoate (1.22 g. 5.2 mmole), ethanol (15 ml.) and 5 ml. of 95 per cent hydrazine (4.75 g., 158 mmole) are refluxed for two hours, cooled, diluted with water (100 ml.) and cooled. The white solid product, 2-(2,2,2-trifluoroethoxy)benzoic acid hydrazide is recrystallized from ethanol, m.p. 102°-104°.
