2,4-Dichloropyrimidine → 2-Chloro-4-(2-phenyl-piperidin-1-yl)-pyrimidine

Participants

Reaction Steps

2-Phenylpiperidine, Intermediate 15, (0.5 g, 2.52 mmol), 2,4-dichloropyrimidine (0.41 g, 2.77 mmol) and sodium bicarbonate (0.59 g, 5.55 mmol) in dry EtOH (10 mL) were refluxed for 2 hours, under an atmosphere of nitrogen. The mixture was filtered and the filtrate evaporated in vacuo to give a yellow oil. The oil was purified by flash chromatography (EtOAc and isohexane (1:3)/silica) to give the title compound as a colourless oil (46 g, 66%).
