Hydrochloric Acid → 2-(1H-Inden-6-yl)-1,3-thiazole

Participants

Reaction Steps

To a solution of 5-(1,3-thiazol-2-yl)indan-1-ol (900.00 mg, 0.0041420 mol) in tetrahydrofuran (20.00 mL) was added a 1.0 M solution of hydrogen chloride in water (20.00 mL). The reaction mixture was heated to reflux overnight. After cooling down to room temperature, the reaction was quenched with 30 mL of 1 N NaOH aqueous solution. The organic layer was separated and the aqueous phase was extracted with EtOAc (3×30 mL). The combined extracts were washed with brine, dried over anhydrous MgSO4, filtered, and evaporated under reduced pressure to afford the desired product (381 mg, 46%). LC-MS [M+1]=200.2.
