Participants

Reaction Steps

Tetrapropylammonium perruthenate (0.16 g, 0.46 mmol) was added to a solution of 4-Hydroxy-3-(4-hydroxymethyl-phenyl)-6-oxo-3a,6,7,7a-tetrahydro-thieno[2,3-b]pyridine-5-carbonitrile (0.55 g, 1.84 mmol) and 4-methylmorpholine N-oxide (0.65 g, 5.52 mmol) in 2:1 mixture of dichloromethane/N,N-dimethylacetamide (33 mL) at room temperature. The reaction was stirred till complete consumption of the starting alcohol, filtered over celite, filtrate washed with 1N HCl, dried (MgSO4) and concentrated to a brown solid. MS (ESI) m/e 294.9 (M−H)+; 1H NMR (300 MHz, DMSO-d6): δ ppm 12.01 (br s, 1H), 10.04 (s, 1H), 7.87 (d, J=9, 2H), 7.66 (d, J=9, 2H), 7.07 (s, 1H).
