Reaktionsschritte

To a stirring solution of ethyl 2,2,2-trifluoroethanethioamide (0.35 g, 2.71 mmol) in THF (12 ml) was added ethyl bromo pyruvate (0.375 ml, 2.98 mmol) at RT. Reaction mixture was heated at 90-100° C. for 16 h. Reaction mixture was diluted with water and DCM. The organic layer was separated and distilled out to get crude product which was column purified using 0-2% EtOAC in hexane to get titled compound in 42% yield.
