Diisopropylethylamine → 1-(5-tert-Butyl-2-{3-[2-(tetrahydro-pyran-2-yloxy)-ethoxy]-phenyl}-2H-pyrazol-3-yl)-3-{(1S,4R)-4-[3((S)-3-methyl-morpholin-4-yl)-[1,2,4]triazolo[4,3-a]pyridin-6-yloxy]-1,2,3,4-tetrahydro-naphthalen-1-yl}-urea

Reaction Steps

A mixture of Intermediate 139c (125 mg, 0.33 mmol), Intermediate 39b (177 mg, 0.33 mmol) and DIPEA (115 μL, 0.66 mmol) in dioxane (3 mL) was stirred at 80° C. overnight. After cooling, the reaction mixture was partitioned between water and DCM. The aqueous phase was extracted with EtOAc (×3) and the combined organic layers were washed with brine, dried (MgSO4) and concentrated in vacuo. The resultant residue was purified by FCC on silica, using a gradient of 0-10% MeOH in DCM, to afford the title compound (214 mg, 85%). LCMS (Method 4): Rt 3.65 min, m/z 765 [MH+].
