Procedure

1-(3-Dibenzylamino-2,6-difluoro-phenyl)-2-[1,3]dithietan-2-ylidene-2-pyridin-4-yl-ethanone (1.26 g, 2.44 mmol) was suspended in absolute ethanol (10 mL). Hydrazine monohydrate (0.473 mL, 9.755 mmol, 4 eq) was added dropwise and the mixture was stirred at 60° C. for 2 hours. The suspension was concentrated under reduced pressure, taken up with toluene (2×20 mL) and evaporated to dryness. The crude product (1.35 g) was used in the following step without further purification.
