Procedure

To a solution of 4-(3-fluoropyrazin-2-yl)tetrahydro-2H-pyran-4-ol (0.1 g, 0.505 mmol) in DMSO (1 mL) was added 4-(benzo[d]thiazol-2-ylamino)phenol (0.183 g, 0.757 mmol) and cesium carbonate (0.329 g, 1.009 mmol). The resulting mixture was heated to 80° C. overnight. Reaction mixture was diluted with DCM and washed with alternating washes of water and brine to remove DMSO. Purification by Biotage (0-10% MeOH/DCM) produced product. MS (ESI, pos. ion) m/z: 421.1 (M+1). IC50 (uM) +++++.
