실험 절차

1.9 g (8 mmol) of 3-benzoylamino-2-chloropyridine, prepared in stage A, are added to the PPSE solution and then brought to reflux for 15 hours. The 1,2-dichlorobenzene is then evaporated off under vacuum. The residue is treated with a water/ice mixture. The pH of the solution is adjusted to 7-8 with 5% sodium bicarbonate solution. The precipitated product is filtered off and then recrystallized in cyclohexane.
