Reaction Steps

To a solution of 3-(tert-butyldiphenylsilyloxy)-1-phenylpropan-1-one (1.98 g, 5.10 mmol) in 20 mL of a 3:1 mixture of EtOH:DCM was added 2,5-difluorobenzothiohydrazide (0.800 g, 4.25 mmol). The mixture was allowed to stir capped, at room temperature for 60 hours, then uncapped for 48 hours and then concentrated in vacuo. The residue was purified by flash column chromatography (Hexanes) to afford the desired product as an orange oil, 2.19 g, 92% which was contaminated with 3-(tert-butyldiphenylsilyloxy)-1-phenylpropan-1-one. The compound was carried forward to the next step without further purification.
