HCID 94041Methyl 3-thienylacetate

Procedure

To 2-(thiophen-3-yl)acetic acid in MeOH at 0° C. was added TMS-CH2N2. The solution was stirred for 3 hours then quenched with a few drops of AcOH. The solvents were evaporated. Column chromatography (SiO2, 3-15% EtOAc/Hex) gave pure methyl 2-(thiophen-3-yl)acetate (E41).
