実験手順

To a solution of 3-fluoro-4-(trifluoromethyl)benzaldehyde (5.7 g, 29.7 mmol) in DCM (60 mL) was added (S)-2-methylpropane-2-sulfinamide (7.19 g, 59.3 mmol) and copper (II) sulfate (18.94 g, 119 mmol). The suspension was stirred at rt under N2 for 20 h. The suspension was then filtered through Celite® brand filter agent, and the solids were washed with DCM (2×20 mL). The filtrates were concentrated and purified by ISCO (120 g, SiO2, 10-50% EtOAc/hexanes) to give (S,E)-N-(3-fluoro-4-(trifluoromethyl)benzylidene)-2-methylpropane-2-sulfinamide as a white solid.
