Reaction Steps

3-Hydroxy-N-(3-isopropylphenyl)-4-methylbenzamide (100 mg, 0.371 mmol), cesium carbonate (220 mg, 0.676 mmol) and 3-(1-benzyl-1H-pyrazol-4-yl)-2-chloropyridine (91.0 mg, 0.338 mmol) were combined in an argon-purged sealed tube. DMSO (1.5 mL) was added and the mixture was heated to 130° C. for 23 hours. The cooled reaction was diluted with EtOAc and water and then neutralized with TFA (pH˜7). The separated organic layer was dried over anhydrous sodium sulfate, filtered and concentrated. The residue was purified first by silica gel chromatography (1:1 MTBE/benzene) followed by trituration of the resulting solid with 20:1 hexanes/EtOAc to yield 3-(3-(1-benzyl-1H-pyrazol-4-yl)pyridin-2-yloxy)-N-(3-isopropylphenyl)-4-methylbenzamide as an off-white solid. MS m/z=503 [M+1]+. Calc'd for C32H30N4O2: 502.62.
