Reaction Steps

To a solution of 1-isopropyl-4-[2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a-diaza-benzo[e]azulen-8-yl]-1,2,5,6-tetrahydro-pyridine-3-carboxylic acid amide (153 mg, 0.33 mmol) in IMS (denatured ethanol) (10 mL) was added platinum (IV) oxide (15 mg, 0.06 mmol). The reaction mixture was heated at 50° C. under an atmosphere of hydrogen. The reaction mixture was cooled to RT, filtered through Celite® and the filtrate concentrated in vacuo. The resultant residue was subjected to flash chromatography (SiO2, gradient 10 to 20% methanol in DCM) to give 403 (80 mg, 52%). LCMS: RT=2.61 min, [M+H]+=464. 1H NMR 400 MHz (DMSO-d6) δ: 8.38 (1 H, d, J=8.33 Hz), 8.15 (1 H, s), 8.04 (1 H, s), 7.04 (1 H, dd, J=8.35, 1.82 Hz), 6.89 (1 H, d, J=1.72 Hz), 5.86 (1 H, m), 4.57-4.48 (4 H, m), 3.57 (2H, t, J=12.74 Hz), 3.42 (1 H, m), 3.31 (1 H, m), 3.25 (1 H, m), 3.22 (1 H, m), 3.04 (1 H, s), 2.60 (1 H, d, J=13.63 Hz), 1.96 (1 H, s), 1.50 (6 H, dd, J=6.59, 3.63 Hz), 1.30 (3 H, d, J=6.70 Hz), 1.22 (3 H, d, J=6.70 Hz)
