Versuchsvorschrift
To a solution of 1.0 mmol 2-isopropylthiophenol and 2.2 mmol TMEDA in 2 mL cyclohexane was added 2.2 mmol n-BuLi. Then after stirring 24 h it was added to solid CO2 and stirred for 16 h when extraction and chromatography provided 2-mercapto-3-isopropylbenzoic acid. The methyl ester of this was treated as in example 3 to provide the title compound.
