To a solution of Methyl [(4S)-6-(4-chlorophenyl)-1-methyl-8-(methyloxy)-4H-[1,2,4]triazolo[4,3-a][1,4]benzodiazepin-4-yl]acetate (for a preparation see Reference compound G) (7.4 g, 18.1 mmol) in THF (130 mL) at room temperature was added 1N NaOH (36.2 mL, 36.2 mmol). The reaction mixture was stirred at this temperature for 5 h before being quenched with 1N HCl (36.2 mL) and concentrated in vacuo. Water is then added and the aqueous layer was extracted with DCM (×3) and the combined organic layers were dried over Na2SO4, filtered and concentrated under reduced pressure to give the title compound (7 g, 98% yield) as a pale yellow solid.
