실험 절차

A solution of ethyl [3,5-bis(1,1-dimethylethyl)-4-hydroxyphenoxy]acetate (2.5 g, 8.1 mmol) and hydrazine monohydrate (1.2 mL, 24.3 mmol) in ethanol (40 mL) is heated at 65°-75° C. for 8 hours. The reaction mixture is cooled and poured into 500 mL of water. The solids are filtered and washed twice with water. The white solid is dried overnight at 50° C. in vacuo to give 2.1 g (87%) of [3,5-bis(1,1-dimethylethyl)-4-hydroxyphenoxy]-acetic acid hydrazide; mp 141.0°-142.5° C.
