Procedure

To a solution of 4-[2-(2-isopropyl-5-methyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a-diaza-benzo[e]azulen-8-yl]-piperidine-1-carboxylic acid tert-butyl ester (569 mg, 1.16 mmol) in dioxane (15 mL) and methanol (5 mL) was added 4M HCl in dioxane (15 mL) and the reaction mixture stirred for 20 h at RT before being concentrated in vacuo. The resultant residue was triturated in a mixture of diethyl ether and methanol to give 2-(2-Isopropyl-5-methyl-2H-[1,2,4]triazol-3-yl)-8-piperidin-4-yl-4,5-dihydro-6-oxa-1,3a-diaza-benzo[e]azulene Hydrochloride as a tan solid (212 mg, 43%). LCMS: RT=2.34/2.66 min, M+H+=393.
