Procedure

2-(2-Isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene-9-carbaldehyde (0.354 g, 1.04 mmol) was dissolved in THF (7 mL) and treated with (trifluoromethyl)trimethylsilane (0.154 mL, 1.04 mmol) followed by TBAF (1M, 0.02 mL, 0.02 mmol). Stirred the resulting reaction mixture at ambient temperature for 2 h. Concentrated in vacuo and re-dissolved in DMF and purified by reverse phase HPLC to give 25.6 mg (6% yield) of 329. LC/MS(ESI+): m/z 411 (M+H). 1H NMR (400 MHz, DMSO) δ 8.55 (s, 1H), 8.10 (s, 1H), 7.41 (d, J=8.4, 1H), 7.10 (d, J=8.3, 1H), 6.80 (s, 1H), 5.80 (dt, J=13.1, 6.5, 1H), 5.21 (d, J=6.7, 1H), 4.39 (t, J=4.9, 2H), 3.45 (t, J=4.9, 2H), 1.55 (d, J=6.5, 6H)
