Reaction Steps

To a glass microwave vial was added benzo[d]thiazol-2-yl(4-(3-bromopyridin-2-yloxy)phenyl)methanone (1.0902 g, 2.65 mmol), 2-(3,6-dihydro-2H-pyran-4-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (1.114 g, 5.30 mmol), trans-dichlorobis(triphenylphosphine) palladium (II) (0.149 g, 0.212 mmol), and sodium carbonate (0.843 g, 7.95 mmol) in DMF (6.63 mL) and water (2.209 mL). The reaction mixture was stirred and heated in a Biotage Initiator microwave reactor at 120° C. for 20 min. Solvent was evaporated. The crude product was adsorbed onto a plug of silica gel and chromatographed through a Biotage pre-packed silica gel column (40S), eluting with a gradient of 5% to 50% EtOAc in hexane, to provide benzo[d]thiazol-2-yl(4-(3-(3,6-dihydro-2H-pyran-4-yl)pyridin-2-yloxy)phenyl)methanone. MS (ESI, pos. ion) m/z: 414.8 (M+1).
