To a solution of 2-[7-(3-fluoro-phenylsulfanyl)-1-methyl-1,2,3,4-tetrahydro-benzofuro[2,3-c]pyridin-1-ylmethyl]isoindole-1,3-dione (0.150 g, 0.317 mmol) in methanol (10.0 mL, 247 mmol) was added a solution of Oxone® (0.488 g, 0.794 mmol) in water (5.0 mL, 280 mmol) and the reaction mixture was stirred at room temperature overnight. After 3 h, the reaction was filtered, concentrated, and extracted with DCM/sat. aq. NaHCO3. The organic layer was dried, concentrated and purified by chromatography to afford 2-[7-(3-fluoro-benzenesulfonyl)-1-methyl-1,2,3,4-tetrahydro-benzofuro[2,3-c]pyridin-1-ylmethyl]isoindole-1,3-dione as an off-white solid. A suspension of 2-[7-(3-fluoro-benzenesulfonyl)-1-methyl-1,2,3,4-tetrahydro-benzofuro[2,3-c]pyridin-1-ylmethyl]isoindole-1,3-dione (0.015 g, 0.030 mmol) in ethanol (5.00 mL, 85.6 mmol) was refluxed with hydrazine monohydrate (0.040 mL, 0.80 mmol). After 4 h, the reaction was cooled, filtered, rinsed with MeOH, and the filtrate concentrated and dried under vacuum to afford a yellowish white solid. mp>250° C. dec.; MS m/z 375 [M+H]+. 1H-NMR (400 MHz, CDCl3): δ 1.5 (s, 3H), 2.7 (m, 2H), 3.15 (m, 1H), 3.36 (m, 1H), 4.0 (d, J=14 Hz, 1H), 4.15 (d, J=14 Hz, 1H), 7.2-8.0 (m, 7H)
