Versuchsvorschrift
The subtitle compound was prepared by using 2-chloro-4-fluorobenzaldehyde (1.16 g) in dry DMF (20 ml). The mixture was treated with sodium thiomethoxide (0.52 g) and heated to 50° C. for 2 hours. The mixture was diluted with water, extracted with ethyl acetate, dried and concentrated under reduced pressure to give a solid. The residue was purified by chromatography on silica eluting with isohexane/diethylether 2:1 to give a white solid, yield 0.70 g.
