Reaction Conditions

Reaction Steps

A suspension of N-(4-(3-iodopyridin-2-yloxy)phenyl)benzo[d]thiazol-2-amine (493 mg, 1.107 mmol), cyclopent-2-enol (373 mg, 4.43 mmol), potassium acetate (217 mg, 2.214 mmol), tetrabutylammonium chloride (338 mg, 1.218 mmol) and Palladium (II) acetate (24.86 mg, 0.111 mmol) in acetonitrile (3 mL) and water (0.300 mL) was degassed and backfilled with argon. The reaction was heated to 90° C. for 18 h. Palladium (II) acetate (24.86 mg, 0.111 mmol) was added, and the reaction was capped, degassed and filled with argon, and heated to 135° C. in a microwave for 1 h. The crude reaction mixture was diluted with dichloromethane (75 mL) and washed with brine (75 mL), dried over MgSO4, concentrated in vacuo and purified by silica gel chromatography (eluant: 35-50% EtOAc/hexane), affording a white solid. It was further purified on a prep HPLC system (and free-based by partitioning between dichloromethane and saturated sodium bicarbonate solution), affording the product as a white solid. MS (ESI, pos. ion) m/z: 402.1 (M+1). IC50 (uM) +++++.
