Reaction Steps

A solution of trifluoro-methanesulfonic acid 2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a,9-triaza-benzo[e]azulen-8-yl ester (100 mg, 0.23 mmol) in NMP was treated with 2M methylamine in THF (1.8 mL, 0.9 mmol) and heated at 85° C. for 20 h then diluted with water and stirred for 4 h. The precipitate was collected by filtration and dried in vacuo to give 416 as a white solid (19.5 mg, 28%). LCMS: RT=2.26 min, [M+H]+=326. 1H NMR 400 MHz (DMSO-d6) δ: 9.02 (1 H, s), 7.88 (1 H, s), 7.80 (1 H, s), 6.70 (1 H, br, m), 5.95 (1 H, s), 5.91-5.90 (1 H, m), 4.47 (4 H, q, J=6.12 Hz), 2.78 (3 H, d, J=4.86 Hz), 1.47 (6 H, d, J=6.60 Hz)
