Procedure

To a solution of methyl 2-(2-isopropyl-5-methyl-1,2,4-triazol-3-yl)-5,6-dihydroimidazo[1,2-d][1,4]benzoxazepine-9-carboxylate; (4.50 g, 12.2 mmol) in Tetrahydrofurane; (100 mL) was added a slurry of Lithium Hydroxide (880 mg, 36.7 mmol) in water (20 mL). The reaction mixture was stirred at room temperature for 1 hour. LC-MS analysis of the reaction mixture showed no more starting material. The solvent was removed and the residue was used in the next step without further purification.
