tert-Butyldimethylsilyl chloride (12.66 g) was added portionwise to 2-(2-thienyl)ethanol (9.0 g) and imidazole (5.7 g) in DMF (35 mL). The resulting solution was stirred for 18 h. The reaction mixture was partitioned between ethyl acetate and water. The organic layer was washed with water, dried over sodium sulphate and the solvents evaporated in vacuo. Purification was by silica gel chromatography, eluting with 99:1 to 96:4 ethyl acetate:isohexane to give the subtitled compound as a clear oil. Yield 16 g.
