To a solution of 2,5-dichloro-N-[2-(propan-2-ylsulfonyl)phenyl]pyrimidin-4-amine (prepared as in Example 17: 50 mg, 0.14 mmol) in 1 mL of 2-methoxyethanol was added 4-(dimethylphosphoryl)-aniline (0.025 g, 0.14 mmol) and 0.12 ml of 2.5M HCl in EtOH. The mixture was heated in a sealed tube at 140° C. for 1 h. The mixture was basified with saturated sodium bicarbonate solution, and extracted with ethyl acetate. The organic layer was purified by prep-HPLC to give the final product (0.100 g, 15% yield). MS/ES+: m/z=478.
