Sodium hydride → HCID 66742678, compound

Participants

Reaction Steps

To a solution of (2-bromothiazol-5-yl)methanol (4.85 g, 25 mmol) and 4-chloro-bicyclo[3.2.1]oct-3-en-2-one (3.92 g, 25 mmol) in anhydrous tetrahydrofuran (100 ml) is added, in small portions, sodium hydride (60% dispersion in oil, 1.00 g, 25 mmol) at 0° C. The reaction mixture is stirred overnight and allowed to warm to room temperature. Silica gel is added to the crude reaction mixture, the solvent is evaporated under reduced pressure and the residue is purified by flash chromatography on silica gel to give 4-(2-bromothiazol-5-ylmethoxy)bicyclo[3.2.1]oct-3-en-2-one (6.43 g)
