Participants

Reaction Steps

To a solution of 4-acetyl-2-bromobenzonitrile (4.0 g, 18 mmol) and (S)-2-methylpropane-2-sulfinamide (2.4 g, 20 mmol) in THF (35 mL) was added titanium(IV) isopropoxide (8.1 mL, 36 mmol) and the reaction mixture was heated to 40 C under an atmosphere of nitrogen. After 2 hours, the reaction was cooled to room temperature, diluted in EtOAc, washed with saturated sodium bicarbonate, rochelle's salt, brine, dried over sodium sulfate, filtered and concentrated. Purification by silica gel chromatography gave desired product. MS (M+H)+: observed=327.0/329.0, calculated=327.2/327.2.
