Versuchsvorschrift

Ethyl 5-formylthiophene-2-carboxylate (0.50 g, 2.71 mmol) was made 2.25 M in anhydrous trifluoroethanol and to this stirring solution was added N-methylpiperazine (0.33 g, 3.26 mmol), 1-chloro-4-isocyanobenzene (0.45 g, 3.26 mmol) and acetic acid (0.20 g, 3.26 mmol). The resulting mixture was stirred at ambient temperature overnight. The reaction mixture was concentrated in vacuo then purified by MPLC to give the desired product. MS: cal'd 422, 424 (MH+), exp 422, 424 (MH+).
