Procedure

To a solution of 5-(4-(tetrahydro-2H-pyran-4-yloxy)pyrido[3,2-d]pyrimidin-6-yl)pyridin-3-amine (Intermediate 12) (0.0500 g, 0.155 mmol) in pyridine (0.773 ml) was slowly added 2-chloro-4-fluorobenzene-1-sulfonyl chloride (0.0430 g, 0.186 mmol) at 0° C. After stirred for 1 hour at room temperature, the reaction mixture was diluted with DCM and quenched with 1N. aq HCl. The combined organic layers were washed brine, dried over anhydrous MgSO4, filtered and concentrated in vacuo. The residue was recrystallized from EtOAc-Hexane to give 2-chloro-4-fluoro-N-(5-(4-(tetrahydro-2H-pyran-4-yloxy)pyrido[3,2-d]pyrimidin-6-yl)pyridin-3-yl)benzene-sulfonamide (0.0500 g, 63%) as a purple solid. 1H-NMR (CDCl3, Varian 400 MHz) δ 2.02-2.11 (2H, m), 2.23-2.28 (2H, m), 3.70-3.75 (2H, m), 4.11-4.16 (2H, m), 5.65-5.70 (1H, m), 7.04-7.09 (1H, m), 7.26-7.28 (2H, m), 8.11-8.15 (1H, m), 8.22 (1H, d, J=8.8 Hz), 8.37 (1H, d, J=8.8 Hz), 8.54 (1H, s), 8.60 (1H, s), 9.16 (1H, s). m/z=516.1 [M+1]+.
