Versuchsvorschrift

Methyl acrylate (1.1 g, 12.6 mmol) and triethylamine (0.5 mL, 0.4 mmol) are sequentially added to a room temperature solution of 2,6-bis(1,1-dimethylethyl)-4-mercaptophenol (3.0 g, 12.6 mmol) in acetonitrile (6 mL). The reaction is stirred for 1.5 hours and then evaporated under high vacuum to give 3.7 g (90%) of the crude product. A small portion is chromatographed on a silica column with ethyl acetate/hexane (1/9) to afford an analytically pure sample of methyl 3-[[3,5-bis(1,1-dimethylethyl)-4-hydroxyphenyl]thio]propanoate, mp 64.0°-66.0° C.
