A solution of 2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-9-{1-[2-(tetrahydro-pyran-2-yloxy)-ethyl]-azetidin-3-yl}-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene (110 mg, 0.22 mmol) in MeOH (3 mL) and DCM (3 mL) was treated with 4N HCl/dioxan (2 mL, 8 mmol) and the mixture left to stand for 3 hours then concentrated in vacuo. The resultant residue was triturated with diethyl ether and dried under vacuum. Further purification by flash chromatography (SiO2, 0-10% 2N NH3/MeOH in DCM) gave 376 (29 mg, 32%). LCMS: RT=6.96 min, [M+H]+=412. 1H NMR δ (ppm) (CDCl3): 8.31 (1 H, d, J=2.34 Hz), 7.90 (1 H, s), 7.15 (1 H, dd, J=8.27, 2.35 Hz), 7.01 (1 H, d, J=8.26 Hz), 5.94-5.84 (1 H, m), 4.40-4.34 (2 H, m), 3.89-3.83 (2 H, m), 3.84-3.72 (1 H, m), 3.59-3.54 (2 H, m), 3.41-3.36 (2 H, m), 3.28-3.21 (2 H, m), 2.71-2.66 (2 H, m), 1.62 (6H, d, J=6.65 Hz). 1 Exchangeable proton not seen
