Following the procedure of 319, 8-azetidin-3-yl-2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene TFA salt 235, trifluoroethyl triflate and triethylamine were reacted to give 422 isolated as a white solid (105 mg, 52%). LCMS: RT=12.34 min, [M+H]+=450. 1H NMR δ (ppm) (CDCl3): 8.32 (1H, d, J=8.18 Hz), 7.90 (1H, s), 7.10 (1H, dd, J=8.21, 1.86 Hz), 6.98 (1H, d, J=1.83 Hz), 5.93-5.84 (1H, m), 4.39 (2H, t, J=5.05 Hz), 3.90 (2H, t, J=7.29 Hz), 3.82-3.73 (1H, m), 3.42-3.33 (4H, m), 3.04 (2H, q, J=9.39 Hz), 1.61 (6H, d, J=6.63 Hz)
