Reaction Steps

Following the procedure for 212, 2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene-8-carbaldehyde and ethanolamine were reacted to give 285 isolated as a pale yellow solid (131 mg, 47%). LCMS: RT=6.85 min, [M+H]+=386. 1H NMR δ (ppm) (CDCl3): 8.31 (1H, d, J=8.11 Hz), 7.89 (1H, s), 7.12 (1H, d, J=8.19 Hz), 7.02 (1H, s), 5.93-5.82 (1H, m), 4.37 (2H, t, J=5.06 Hz), 3.81 (2H, s), 3.66 (2H, t, J=5.12 Hz), 3.38 (2H, t, J=5.06 Hz), 2.81 (2H, t, J=5.11 Hz), 1.60 (6H, d, J=6.63 Hz). 2 Exchangeable protons not seen.
