Reaction Steps

A mixture of (S)-3-carbamoyl-4-{2-[2-(2,2,2-trifluoro-ethyl)-2H-[1,2,4]triazol-3-yl]-4,5-dihydro-6-oxa-1,3a-diaza-benzo[e]azulen-8-yl}-piperazine-1-carboxylic acid benzyl ester (0.03 g) and 10% Pd/C (0.014 g) in IMS (5 mL) was stirred under an atmosphere of hydrogen at RT for 64 h. The reaction mixture was filtered through Celite® and the filtrate concentrated in vacuo. The resultant residue was subjected to flash chromatography (SiO2, gradient 0 to 20% methanol in DCM) to give 543 (0.005 g, 20%). LCMS: RT=2.49 min, [M+H]+ 463. 1H NMR 400 MHz (MeOD): δ 8.28 (1 H, d, J=9.03 Hz), 8.00 (1 H, s), 7.78 (1 H, s), 6.79 (1 H, dd, J=9.09, 2.63 Hz), 6.56 (1 H, d, J=2.58 Hz), 5.83 (2 H, q, J=8.50 Hz), 4.50-4.43 (3 H, m), 4.30 (1 H, t, J=3.89 Hz), 3.52-3.45 (2 H, m), 3.38 (1 H, dd, J=13.28, 3.28 Hz), 3.34 (1 H, s), 3.13-3.10 (2 H, m), 2.96-2.88 (1 H, m)
