Reaction Steps

General procedure C was followed using isonipecotamide (43 mg, 0.34 mmol), 3,4,dichloropyridine (50 mg, 0.34 mmol), triethylamine (0.14 mL, 1.0 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 (18 mg, 22%), m.p. 210-212° C.; umax (CHCl3)/cm−1 2360, 2342, 1653, 1581 1382, 1223, 1135, 1041; m/z (ESI) C11H15ClN3O requires 240.0898, found [M+H]+ 240.0899.
