関与物質

反応手順

1-t-Butyl-4-piperidone (1.3 g, 8.4 mmol, 1.0 equiv), NaCN (0.61 g, 12.6 mmol, 1.5 equiv), and NH4Cl (0.67 g, 12.6 mmol, 1.5 equiv) were combined in 34 mL of 2 M NH3 in MeOH. The mixture was refluxed for 2 h at which time an additional 34 mL of 2 M NH3 in MeOH was added followed by another 2 h at reflux. The mixture was cooled and filtered. The filtrate was concentrated in vacuo and the residue was triturated with CH2Cl2 and filtered again. The solution was concentrated to a thick red oil which was used without further purification; MS, m/z 182=M+1.
