Procedure

To a 10 mL vial were added 8-(4-chloro-6-morpholino-1,3,5-triazin-2-yl)-3-oxa-8-azabicyclo[3,2,1]octane (311 mg, 1.0 mmol), 4-aminophenylboronic acid pinacol ester (328 mg, 1.5 mmol), Pd(PPh3)4 (58 mg, 5 mol %), 1,2-dimethoxyethane (DME, 2.5 mL) and 2M Na2CO3 aqueous solution (1.5 mL). The resulting mixture was heated at 130° C. for 30 min in microwave oven. The reaction mixture was cooled to room temperature. The aqueous phase was extracted with EtOAc, and the combined organic phases were dried over (MgSO4). The solvent was removed under reduced pressure and the residue was subjected to HPLC separation to give the title compound as off-white solid (280 mg, 76% yield). MS (ESI) m/z 369.2.
