Procedure

A solution of (S)-2-[2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a,9 triaza-benzo[e]azulen-8-yloxy]-propionic acid tert-butyl ester (206 mg, 0.47 mmol) in HCl in dioxane (4N, 5 mL) was heated at 50° C. for 2 h. The reaction mixture was concentrated in vacuo and the residue triturated with MeCN. The product was collected by filtration and dried in vacuo at 50° C. to yield (S)-2-[2-(2-Isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a,9-triaza-benzo[e]azulen-8-yloxy]-propionic acid as a beige solid (115 mg, 66%). LCMS: RT=2.72 min, [M+H]+=385
