Following the procedure for 473, a mixture of 4-(8-bromo-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulen-2-yl)-2-isopropyl-5-methyl-2,4-dihydro-[1,2,4]triazol-3-one and 4-(8-iodo-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulen-2-yl)-2-isopropyl-5-methyl-2,4-dihydro-[1,2,4]triazol-3-one and 2-methyl-1-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-pyrazol-1-yl]-propan-2-ol were reacted to give 474 isolated as a white solid (34 mg, 59%). LCMS: RT=4.79 min, [M+H]+=481. 1H NMR δ (ppm) (DMSO-d6): 8.15 (1 H, d, J=8.26 Hz), 8.08 (1 H, s), 7.87 (1 H, d, J=0.74 Hz), 7.33 (1 H, dd, J=8.26, 1.84 Hz), 7.22 (1 H, d, J=1.82 Hz), 4.68 (1 H, s), 4.38-4.28 (3 H, m), 3.99 (2 H, s), 3.28 (2 H, m), 2.67 (3 H, s), 1.29 (6 H, t, J=6.68 Hz), 1.05 (6 H, s)
