Following the procedure for 128 without the use of HCl in diethyl ether, 2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,10b-diaza-benzo[e]azulene-9-carbaldehyde was reacted with 2-hydroxy-1-piperazin-1-yl-ethanone to give 132 as a white solid. 1H NMR (CDCl3, 400 MHz): δ 7.95 (s, 1H); 7.86 (d, J=2.0 Hz, 1H); 7.28-7.23 (m, 1H); 7.17 (d, J=8.2 Hz, 1H); 6.86 (s, 1H); 5.73-5.60 (m, 1H); 4.55 (t, J=6.0 Hz, 2H); 4.15 (s, 2H); 3.69 (t, J=4.8 Hz, 2H); 3.64-3.55 (m, 3H); 3.29 (t, J=4.8 Hz, 2H); 3.16 (t, J=6.0 Hz, 2H); 2.55-2.46 (m, 4H); 1.58 (d, J=6.6 Hz, 6H). LCMS: RT=5.70 min, M+H+=452
