Following the procedure for 119, 2-(4-isopropyl-4H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene-8-carbaldehyde and ethanolamine were reacted. After aqueous work-up the resulting gum was triturated with DCM/ether/pentane to give a solid that was filtered off and dried to give 131 as an off-white solid (55 mg, 27%). LCMS: RT=5.54 min, [M+H]+=386. 1H NMR δ (ppm) (CDCl3): 8.37 (1H, s), 8.30 (1H, d, J=8.11 Hz), 7.13 (1H, dd, J=8.15, 1.72 Hz), 7.05 (1H, d, J=1.68 Hz), 5.70-5.63 (1H, m), 4.41 (2H, t, J=5.06 Hz), 3.84 (2H, s), 3.68 (2H, t, J=5.17 Hz), 3.42 (2H, t, J=5.07 Hz), 2.85 (2H, t, J=5.16 Hz), 1.65 (6H, d, J=6.74 Hz). 2 Exchangeable protons not seen
