To a solution of 2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-8-piperidin-4-yl-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene TFA salt 375 (188 mg, 0.37 mmol) and triethylamine (0.18 mL, 1.3 mmol) in IMS (3 mL) was added ethenesulfonic acid dimethylamide and the reaction mixture stirred at RT for 18 h before being concentrated in vacuo. The resultant residue was subjected to flash chromatography (SiO2, gradient 0 to 5% MeOH in DCM) to give 499 as a beige solid (145 mg, 74%). LCMS: RT=3.47 min, [M+H]+=531. 1H NMR δ (ppm) (DMSO-d6): 8.23 (1H, d, J=8.19 Hz), 8.05 (1H, s), 7.04 (1H, dd, J=8.26, 1.80 Hz), 6.88 (1H, d, J=1.76 Hz), 5.82-5.72 (1H, m), 4.30 (2H, t, J=5.02 Hz), 3.37 (2H, t, J=5.04 Hz), 3.19 (2H, t, J=7.23 Hz), 2.95 (2H, d, J=10.97 Hz), 2.75 (6H, s), 2.65 (2H, t, J=7.25 Hz), 2.04 (2H, t, J=11.43 Hz), 1.75 (2H, d, J=12.62 Hz), 1.67-1.53 (2H, m), 1.50 (6H, d, J=6.58 Hz). 1H obscured by solvent
