Reaction Steps

A mixture of ethyl 2-((4-chlorophenyl)amino)acetate (10.0 g, 46.8 mmol) and (E)-4-ethoxy-1,1,1-trifluorobut-3-en-2-one (11.0 g, 65.5 mmol) in DCM (150 mL) was heated overnight at 50° C. The resulting mixture was concentrated and then triturated with 20% EtOAc/heptane and the resulting solid filtered and washed with heptane to yield (E)-ethyl 2-((4-chlorophenyl)(4,4,4-trifluoro-3-oxobut-1-en-1-yl)amino)acetate.
