To a solution of (1S,2R)-2-(bromomethyl)-4′-(4-chlorophenyl)-2′,3′,9′-trimethylspiro-[cyclopropane-1,6′-thieno[3,2-f][1,2,4]triazolo[4,3-a][1,4]diazepine](350 mg, 0.758 mmol) in DMF (4 mL) was added ammonium hydroxide (3 mL, 77 mmol) at rt. After 9 h at rt, silica gel was added, and the solvent was removed under vacuum. The dry silica gel was packed, and the product was purified by chromatography (Hexane/EtOAc 5:5 to 0:10 then DCM/MeOH 10:0 to 9:1). A second (EtOAc/toluene/MeOH 4:4:2) and a third chromatography were performed (2-propanol 100%) to give a tan solid (12 mg). LRMS (M+H)+: 398 m/z.
