Procedure

To a solution of 2-[6-(quinolin-7-yloxy)-pyrimidin-4-yl]-5-trifluoromethyl-phenylamine, (Example 163), (0.40 g, 1.1 mmol) in 1,2-dichloroethane (11 mL) was added cyclohexanecarboxaldehyde (0.32 mL, 2.6 mmol, Aldrich) and the mixture was stirred at room temperature for 18 h. NaBH(OAc)3 (0.55 g, 2.6 mmol) was added and stirring was continued for 8 h at 40° C. The reaction was diluted with satd NaHCO3 and H2O, and extracted with EtOAc (2×75 mL). The combined extracts were washed with H2O (75 mL) and brine (75 mL), dried over Na2SO4, filtered and concentrated onto silica gel. Purification by silica gel chromatography (gradient, 10 to 40% EtOAc/hexanes) afforded the title compound as a yellow solid. Mp: 137–138° C. MS (ESI, pos. ion) m/z: 479.2 (M+1).
