Reaction Steps

To a solution of 7-iodo-isothiochroman-4-one (290 mg, 1.0 mmol) in DMF (5 mL) is added Zn(CN)2 (117 mg, 1.0 mmol) and Pd(PPh3)4 (124 mg, 0.1 mmol). The reaction is then heated to 95° C. for 3 hours, at which time it is cooled to room temperature and concentrated to dryness. The resulting residue is purified by silica gel flash chromatography (ethyl acetate-dichloromethane, 1:10 to 3:10) to furnish 4-oxo-isothiochroman-7-carbonitrile; MS: (ESI) m/z 188.2 (M−H)−.
