Methyl-2-(2-{3-[(E)-2-(7-chloro-quinolin-2-yl)-vinyl]-phenyl}-2-hydroxy-ethylsulfanyl)-benzoate → Methyl-2-(2-{3-[(E)-2-(7-chloro-quinolin-2-yl)-vinyl]-phenyl}-2-oxo-ethylsulfanyl)-benzoate

Participants

Reaction Steps

To a stirred solution of hydroxy compound 46 (10.0 g, 0.021 mol) in dichloromethane (100 ml) was added in single lot pyridinium chlorochromate (13.44 g, 0.035 mol) and allowed to stir at ambient temperature for 2 hours. The resulting mixture was filtered through a bed of highflow. The residue was washed with dichloromethane (500 ml). The combined filtrate layer was evaporated and subjected to FC to give pale yellow solid 47 (8.0 g, 80%).
