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

Reaction Steps

To a solution of Intermediate 96c (100 mg, 0.25 mmol) in 1,4-dioxane (3.00 mL) was added DIPEA (89.0 μL, 0.51 mmol) and Intermediate 39b (133 mg, 0.25 mmol). The reaction was heated to 70° C. overnight then cooled and partitioned between EtOAc and water. The aqueous layer was then extracted with EtOAc (3×). The combined organic layers were washed with brine, dried (MgSO4), filtered and evaporated in vacuo. The residue was purified by FCC using 0-8% MeOH in DCM to give the title compound. LCMS (Method 4): Rt 4.09 min, m/z 777 [MH+].
