Procedure

To a solution of 3-[2-(5-benzyloxycarbonylamino-2-isopropyl-2H-[1,2,4]-triazol-3-yl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulen-8-yl]-azetidine-1-carboxylic acid tert-butyl ester (504 mg, 0.82 mmol) in DCM (10 mL) was added 4N HCl in dioxan (2 mL) at RT. After stirring for 2 hours MeOH (2 mL) and 4N HCl in dioxan (3 mL) were added to the mixture. After stirring for 60 minutes the reaction mixture was concentrated in vacuo. The resulting solid was treated with ether, collected by filtration and dried under vacuum to afford [5-(8-azetidin-3-yl-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulen-2-yl)-1-isopropyl-1H-[1,2,4]triazol-3-yl]-carbamic acid benzyl ester hydrochloride salt (379 mg, 84%). LCMS: RT=3.04 min, [M+H]+=517
