実験手順

A solution of 5 g (19 mmol) of (4-iodo-phenyl)-acetic acid in 50 mL of methanol (MeOH) was added dropwise 3.5 mL (48 mmol) of thionyl chloride (SOCl2), and the resulting mixture was stirred at rt for 36 h, after which time analysis by thin layer chromatography (TLC) indicated product formation. The mixture was concentrated to give 4.5 g (86% yield) of (4-iodo-phenyl)-acetic acid methyl ester as a pale beige oil as indicated by 1H NMR.
