Methyl 3-mercaptopropionate → Methyl 2-methoxy-3-(2-carbomethoxyethylthio)-3-[2-(8-phenyloctyl)phenyl]propanoate

Participants

Reaction Steps

To trifluoroacetic acid (100 ml) under argon and cooled to 0° C., was added methyl 3-mercaptopropanoate (0.5 ml, 4.5 mmoles). The mixture was stirred for 10 minutes, after which the ice bath was removed. Methyl 2-methoxy-3-hydroxy-3-[2-(8-phenyloctyl)phenyl]propanoate (1.5 g, 4 mmoles) was added and the mixture stirred for 18 hours. The reaction mixture was evaporated and diluted in methylene chloride. The organic layer was washed with 10% sodium hydroxide (ice cold) followed by ice water. The organic layer was dried over magnesium sulfate, filtered and evaporated. Flash chromatography on silica gel provided the desired product.
