60 °C

To a solution of 4-(pyridin-2-ylamino)phenol (14.551 g, 78.14 mmol) and 2,3-dichloropyrazine (11.64 g, 78.14 mmol) in DMSO was added CESIUM CARBONATE (30.55 g, 93.77 mmol). The resulting mixture was heated to 60° C. overnight. Aqueous workup was carried out with DCM extraction and washing with alternating water and brine solutions. Purification by Biotage (0-2%, then 2% MeOH/DCM), followed by washing with EtOAc, produced clean product as solid. MS (ESI, pos. ion) m/z: 298.8 (M+1). IC50 (uM) 0.475.
