反応手順

Add sodium hydride (737 mg, 29.23 mmol, 1.10 equivalents, 95%) to a solution containing methyl iodide (1.65 mL, 26.57 mmol, 1.00 equivalents) and (4-bromo-thiophen-2-yl)-methanol (5.13 g, 26.57 mmol, 1.00 equivalents) in tetrahydrofuran (dry, 25 mL). Stir the resulting mixture at room temperature overnight and evaporate. Partition the residue between water (100 mL) and dichloromethane (100 mL). Extract the aqueous layer with dichloromethane (100 mL), combine the organic layers, dry over magnesium sulfate, filter and evaporate to yield the desired product as a yellow oil.
