Procedure

To a solution of 2,5,6-trichloro-N-(5-methyl-1H-pyrazol-3-yl)pyrimidin-4-amine (Method 39; 2.0 g, 8.2 mmol) in absolute EtOH (40 ml) were added DIEA (2.5 ml) and (15)-1-(5-fluoropyridin-2-yl)ethanamine (Method 6; 1.2 g, 8.2 mmol) and the resulting solution was heated to 140° C. for 12 hours. The mixture was partitioned between EtOAc and H2O, the organic layer was washed with brine and dried. The solvents were removed under reduced pressure to give an oil which was purified by Gilson (20-75% acetonitrile/H2O, 35 min) to give the titled compound as solid (762 mg). m/z: 383.
