Procedure

A mixture of 1-pyridin-2-ylpiperazine (24 mg, 0.15 mmol, Aldrich), N-(2,3-dichlorophenyl)-2-chloroacetamide (48 mg, 0.20 mmol, Maybridge) and sodium carbonate (50 mg) in N,N-dimethylformamide/water (2:1, 2 mL) was shaken at room temperature for 18 hours. The resulting mixture was decanted, concentrated under reduced pressure the residue purified by preparative HPLC to provide 9 mg (16%) of the desired product as a trifluoroacetic acid salt. 1H NMR (500 MHz, DMSO-d6) δ 2.62 (t, J=4 Hz, 4H), 3.23 (s, 2H), 3.58 (t, J=4 Hz, 4H), 6.63 (t, J=5 Hz, 1H), 6.83 (d, J=6 Hz, 1H), 7.55 (t, J=6 Hz, 1H), 7.68 (m, 2H), 7.88 (m, 2H), 8.12 (d, J=5 Hz, 1H), 10.12 (s, 1H); MS (ESI/APCI+) m/e 365 (M+H)+.
