A solution of [5-(8-bromo-4,5-dihydro-6-oxa-1,3a-diaza-benzo[e]azulen-2-yl)-1-isopropyl-1H-[1,2,4]triazol-3-yl]-methanol (67 mg, 0.17 mmol) in IMS was degassed then treated with Pd/C (10% wt. 120 mg) before being stirred at RT under an atmosphere of hydrogen for 18 h. The reaction mixture was filtered through Celite®, washing with DCM, the filtrate concentrated in vacuo. The resultant residue was subjected to flash chromatography (SiO2, gradient 0 to 7% methanol in DCM) to give 315 as a white solid (13 mg, 24%). LCMS: RT=3.79 min, [M+H]+=326. 1H NMR 400 MHz (DMSO-d) δ: 8.42 (1H, dd, J=8.03, 1.74 Hz), 7.91 (1H, s), 7.33 (1H, ddd, J=8.16, 7.12, 1.77 Hz), 7.16-7.16 (1H, m), 7.06 (1H, dd, J=8.18, 1.21 Hz), 5.86 (1H, t, J=6.61 Hz), 5.21 (1H, t, J=6.03 Hz), 4.52 (4H, q, J=5.81 Hz), 4.42 (2H, d, J=6.00 Hz), 1.48 (6H, d, J=6.61 Hz)
