Reaction Steps

General procedure C was followed using N-ethylpiperazine (31 mg, 0.27 mmol), 3,4,5-trichloropyridine (50 mg, 0.27 mmol), triethylamine (0.76 μL, 0.54 mmol) and NMP (1.5 mL). The crude product was purified by flash column chromatography on silica gel (hexane/EtOAc, 1:1) to furnish the title compound as a colourless oil (47 mg, 66%), umax (CHCl3)/cm−1 2975, 2820, 1559, 1448, 1245, 1151, 957; m/z (ESI) C11H16Cl2N3 requires 260.0716, found [M+H]+ 260.0719.
