実験手順

Methyl 4-[4-[[1-[[3,5-bis(1,1-dimethylethyl)-4-hydroxyphenyl]thio]-1-methylethyl]thio]-2,6-bis(1,1-dimethylethyl)phenoxy]butyrate (0.95 g, obtained above) was dissolved in THI/MeOH/H2O (4:1;1, 15.4 mL) and lithium hydroxide hydrate (0.19 g) was added. The mixture was stirred at room temperature for four hours and then acidified with 0.3 N HCl. The mixture was poured into brine and extracted with ethyl acetate. The organic phase was dried over sodium sulfate and evaporated to give 0.60 g of 4-[4-[[1-[[3,5-bis(1,1-dimethylethyl)-4-hydroxyphenyl]thio]-1-methylethyl]thio]-2,6-bis(1,1-dimethylethyl)phenoxy]butyric acid (Compound A) as a solid.
