Procedure

To a solution of [2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a-diaza-benzo[e]azulen-8-ylamino]-acetic acid methyl ester (407 mg, 0.43 mmol) in dioxane (1 mL) and water (1 mL) was added lithium hydroxide monohydrate (36 mg, 0.86 mmol) and the reaction mixture stirred at RT for 18 h. Water was added and the reaction mixture extracted with DCM. The aqueous phase was filtered and concentrated in vacuo to give [2-(2-Isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a-diaza-benzo[e]azulen-8-ylamino]-acetic acid lithium salt (130 mg, 81%). LCMS: RT=2.30 min, [M+H]+=369.
