1,4-Oxazepine → 1-{5-tert-Butyl-2-[3-(2-[1,4]oxazepan-4-yl-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 salt

Reaction Steps

A solution of Intermediate 154a (50.5 mg, 66 μmol) and [1,4]oxazepine (70 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 (27 mg, 53%). LCMS (Method 5): Rt 3.68 min, m/z 762 [MH+]. 1H NMR (400 MHz, d6-DMSO): 0.91 (3H, d, J=6.2 Hz), 1.27 (9H, s), 1.46-1.54 (2H, m), 1.62-2.17 (12H, m), 2.67-2.72 (3H, m), 2.86 (2H, t, J=6.0 Hz), 2.88-2.94 (1H, m), 3.12-3.19 (1H, m), 3.28-3.34 (1H, m, obscured by water peak), 3.53-3.58 (2H, m), 3.61 (2H, t, J=6.0 Hz), 4.09 (2H, t, J=6.1 Hz), 4.77-4.86 (1H, m), 5.52 (1H, t, J=4.3 Hz), 6.33 (1H, s), 6.94-6.99 (1H, m), 7.05-7.12 (2H, m), 7.19 (1H, dd, J=8.6 Hz, 2.0 Hz), 7.24-7.42 (5H, m), 7.64 (1H, d, J=9.8 Hz), 7.69 (1H, d, J=2.0 Hz), 8.17 (1H, s), 8.18 (1H, s).
