HCID 866873101-(5-tert-Butyl-2-{3-[2-(ethyl-methyl-amino)-ethoxy]-phenyl}-2H-pyrazol-3-yl)-3-{(1S,4R)-4-[3-((S)-2-methyl-piperidin-1-yl)-[1,2,4]triazolo[4,3-a]pyridin-6-yloxy]-1,2,3,4-tetrahydro-naphthalen-1-yl}-urea formate saltYield 50%

Procedure

A solution of Intermediate 154a (50.5 mg, 66 μmol) and N-ethylmethylamine (40 mg, 0.68 mmol) in THF (1 mL) was heated at 60° C. for 48 h in a sealed vessel. The reaction mixture was concentrated in vacuo and the residue purified by MDAP (Method 7) to give the title compound as a white solid (24 mg, 50%). LCMS (Method 5): Rt 3.69 min, m/z 720 [MH+]. 1H NMR (400 MHz, d6-DMSO): 0.91 (3H, d, J=6.3 Hz), 0.94 (3H, t, J=7.2 Hz), 1.27 (9H, s), 1.46-1.55 (2H, m), 1.64-1.72 (2H, m), 1.76-2.09 (6H, m), 2.19 (3H, s), 2.41 (2H, quart, J=7.0 Hz), 2.68 (2H, t, J=4.7 Hz), 2.86-2.94 (1H, m), 3.12-3.19 (1H, m), 3.29-3.34 (1H, m, obscured by water peak), 4.08 (2H, t, J=6.1 Hz), 4.77-4.86 (1H, m), 5.52 (1H, t, J=4.4 Hz), 6.33 (1H, s), 6.94-6.98 (1H, m), 7.05-7.13 (3H, m), 7.19 (1H, dd, J=9.6 Hz, 2.2 Hz), 7.23-7.42 (5H, m), 7.64 (1H, d, J=10.2 Hz), 7.69 (1H, d, J=2.2 Hz), 8.13 (1H, s), 8.18 (1H, s).
