Participants

Reaction Steps

The title compound is prepared in accordance with the procedures set forth in Moreira, R. et al., Tet. Lett. , (1994), 35, 7107–7110. Thus, a mixture of 2-piperidinone (1.0 g, 10.09 mmol) and paraformaldehyde (500 mg) is refluxed in anhydrous THF (30 mL) and chlorotrimethylsilane (30 mL) overnight under N2. Concentrate the solvent under vacuum to give N-(chloromethyl)-2-piperidone as an oil (1.30 g).
