Reaction Steps

5,6-Dimethyl-3-ethoxycarbonylmethyl-2-(3-pyridyl)-isoindolin-1-one [IUPAC name: ethyl 2-[5,6-dimethyl-3-oxo-2-(3-pyridinyl)-2,3-dihydro-1H-isoindol-1-yl]acetate] (0.10 g, 0.31 mmol) and 2,4-bis(4-methoxyphenyl)-1,3-dithia-2,4-diphosphetane-2,4-disulfide (69 mg, 0.17 mmol) were heated under reflux in toluene (1.5 ml) under an argon atmosphere for 1 hr. The reaction solution was concentrated under reduced pressure, and the residue was purified by silica gel chromatography (chloroform:acetone=10:1) to give 97 mg of the title compound.
