Procedure

3-{2-[2-(2,4-Difluoro-phenyl)-2H-[1,2,4]triazol-3-yl]-4,5-dihydro-6-oxa-1-thia-10-aza-benzo[e]azulen-9-ylamino}-azetidine-1-carboxylic acid tert-butyl ester (558 mg, 1.0 mmol) was dissolved in EtOAc (10 mL). Hydrogen chloride dissolved in Ethyl acetate (EtOAc—HCl, 10 mL) was added by drop to the solution and the reaction mixture was stirred at room temperature for 2 h. The reaction mixture was filtered to gather the solid which was washed with DCM (10 mL) to give 435 (0.43 g, yield: 87%). 1HNMR (DMSO-d6, 400 MHz): δ7.99 (s, 1H), 7.74-7.72 (m, 1H), 7.36-7.27 (m, 2H), 7.14 (s, 1H), 7.00 (d, J=8.8 Hz, 1H), 6.38-6.26 (m, 2H), 4.11-4.09 (m, 6H), 3.56 (s, 1H), 3.02 (t, J=4.8 Hz, 2H). ESI-MS: m/z=453 [M+H+]
