Reaction Steps

To a solution of 4-amino-2-(1-(5-methyl-6-(2,2,2-trifluoroethoxy)pyridin-3-yl)ethyl)-2,3-dihydro-1H-pyrrolo[3,4-c]pyridin-1-one (230 mg, 0.63 mmol, Example-17, single enantiomer) and pyridine (250 mg, 3.1 mmol) in DCM (5 mL) is added 2-chloroacetyl chloride (89 mg, 0.79 mmol) at rt. The mixture is stirred for 1 hour at rt, and the mixture is diluted with water. The mixture is extracted with DCM. The organic layer is washed with brine, dried over sodium sulfate, and filtered. The filtrate is concentrated. The residue is purified by column chromatography on silica gel eluting with n-hexane/EtOAc (3:1 to 1:1) to give 270 mg (96% yield) of the title compound as pale brown solid.
