YieldReaction ConditionsOperation in experiment
99% With 3-chloro-benzenecarboperoxoic acid; In dichloromethane; for 3.25h; To a solution of 4-chlorothieno[2,3- Z>]pyridine (450 mg, 2.65 mmol, 1 eq.) in DCM (14.7 mL) was added 3-chloroperoxybenzoic acid (1.78 g, 7.95 mmol, 3 eq.) over 15 minutes. After three hours, the reaction was quenched with 10% NaS2C>3 solution and washed with 10% K2CO3. The aqueous layer was back extracted with 3: 1 CHCI3/IPA solution. The organic layers were combined, dried (MgS04), filtered and concentrated in vacuo. Purification by flash chromatography on silica gel afforded 500 mg (99%) of the title compound. XH NMR (400 MHz, DMSO-c) delta 8.42 (d, J = 6.6 Hz, 1H), 8.06 (d, J = 5.7 Hz, 1H), 7.65 (d, J = 6.6 Hz, 1H), 7.54 (d, J= 5.7 Hz, 1H); ES- MS [M+l]+: 186.4.
