4-Chloro-7-(3,5-dimethyl-4-isoxazolyl)-6-(methyloxy)-3-quinolinecarboxamide (for a preparation see Intermediate 9) (1.890 g, 5.70 mmol) was dissolved in NMP (5 ml), DIPEA (2.487 ml, 14.24 mmol) was added followed by (tetrahydro-2H-pyran-4-yl)methanamine (0.82 g, 7.12 mmol) and the mixture was heated at 120° C. for 3 h, then cooled and the brown solution loaded onto a 70 g SCX-2 cartridge, the column washed with methanol (200 ml) and then eluted with 2M methanolic ammonia (100 ml) and methanol (100 ml). The eluant was evaporated in vacuo to give a brown solid. This was triturated with EtOAc (30 ml) and the solid collected by filtration to give 7-(3,5-dimethyl-4-isoxazolyl)-6-(methyloxy)-4-[(tetrahydro-2H-pyran-4-ylmethyl)amino]-3-quinolinecarboxamide (1.58 g, 3.85 mmol, 54.1% yield) as brown solid. LCMS (formate) Rt 0.64, MH+ 411
