Procedure
A mixture of 4-amino-2-methyl-1,2-dihydro-3H-pyrrolo[3,4-c]pyridin-3-one (Compound 3108, 62.5 mg, 0.383 mmol) and m-Chloroperbenzoic acid (145 mg, 0.843 mmol) in Acetone (10.0 mL) was stirred at rt for 90 minutes. The reaction mixture was concentrated under reduced pressure to an off white solid. The crude material was purified by silica gel chromatography on the combi-flash Rf system using DCM/7 N NH3 in MeOH (100:0→90:10) as eluent. The fractions containing product were combined and concentrated under reduced pressure to yield a white solid (68.3 mg, 99.5%). 1H NMR (DMSO-d6, 400 MHz): δ=8.19 (d, J=6.57 Hz, 1H), 7.02 (br. s., 2H), 6.82 (d, J=6.57 Hz, 1H), 4.41 (s, 2H), 3.01 (s, 3H). MS (ES+): m/z 180.07 [MH+] (TOF, polar).
