Procedure

To a solution of methyl 2-(1-(5-methyl-6-(2,2,2-trifluoroethoxy)pyridin-3-yl)ethyl)-1-oxo-2,3-dihydro-1H-pyrrolo[3,4-c]pyridine-4-carboxylate (300 mg, 0.73 mmol, Step-1, single enantiomer) in THF (8.0 mL) is added 2 M aqueous sodium hydroxide (1.1 mL, 2.2 mmol) at rt, and the reaction mixture is stirred overnight at rt. The reaction mixture is neutralized by the addition of 2 M aqueous hydrochloric acid (1.1 mL, 2.2 mmol). The mixture is extracted with DCM, and the organic layer is dried over sodium sulfate. After filtration, the filtrate, and volatiles are removed to give 297 mg (>99% yield) of the title compound as white solid.
