Procedure

To a solution of 2,5-dichloro-N-[2-(propan-2-ylsulfonyl)phenyl]pyrimidin-4-amine (as prepared in Example 17: 0.040 g, 0.12 mmol) in 1 mL of 2-methoxyethanol was added 4-(dimethylphosphoryl)-2-fluoroaniline (0.023 g, 0.12 mmol) and 49 μL of 2.5 M HCl in ethanol. The mixture was heated in a sealed tube at 90° C. for 16 h. The mixture was basified with 1N NaOH solution, and extracted with ethyl acetate. The organic layers were combined, washed with saturated sodium chloride solution, dried with sodium sulfate, filtered and concentrated. The crude residue was purified by prep-HPLC to afford the final compound (9.0 mg, 22% yield). MS/ES+: m/z=497.
