Procedure

To a solution of 2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-8-{1-[2-(tetrahydro-pyran-2-yloxy)-ethyl]-piperidin-4-yl}-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene (103 mg, 0.20 mmol) in MeOH (2 mL) was added HCl (1 mL, 4N in dioxan) and the reaction mixture stirred at RT for 30 min. The reaction mixture was concentrated in vacuo and the residue freeze dried from MeOH/H2O to give 512 as a solid (136 mg). LCMS: RT=3.16 min, [M+H]+=440 [ad823338] 1H NMR 400 MHz (d6-DMSO) δ: 8.27 (1H, d, J=8.19 Hz), 8.03 (1H, s), 7.04 (1H, dd, J=8.13, 1.84 Hz), 6.89 (1H, d, J=1.75 Hz), 5.79-5.71 (1H, m), 4.31 (2H, t, J=5.0 Hz), 3.74 (2H, t, J=5.0 Hz), 3.57 (2H, d, J=12.01 Hz), 3.37 (2H, t, J=4.96 Hz), 3.08-3.07 (4H, m), 2.79 (1H, t, J=7.80 Hz), 1.98-1.97 (4H, m), 1.49 (6H, d, J=6.59 Hz)
