Versuchsvorschrift
A mixture of 5-iodothiophene-3-carboxylic acid (3.48 g), iodomethane (2.92 g), potassium carbonate (2.84 g) and DMF (35 ml) was stirred at room temperature for 1 day. The reaction mixture was poured into water, and extracted with EtOAc. The extract was washed with brine, dried over MgSO4, concentrated and purified by silica gel column chromatography (hexane/EtOAc) to give the title compound (3.62 g) as a white solid.
