2-Naphthylacetonitrile → tert-Butyl 4-cyano-4-(naphthalen-2-yl)piperidine-1-carboxylate

Participants

Reaction Steps

Combine naphth-2-ylacetonitrile (10 mmol) and 2-chloro-N-(2-chloroethyl)-N-tert-Butoxycarbonyl-ethanamine (11 mmol) in DMSO (30 mL). Add portionwise, NaNH2 (22 mmol). After the addition, stir for an additional 0.5 h. Pour the contents of the flask over ice (150 g). Extract the mixture with dichloromethane. Dry the organic phase over MgSO4, filter, and concentrate in vacuo to give a residue. Purify to give the title compound.
