Procedure

To a solution of (2-nitrovinyl)-cyclohexane (2.63 g, 16.94 mmol), prepared as in J. Org. Chem. 1993, 58, 3850, in dry CH2Cl2 (22 mL), N-Boc piperazine (2.63 g, 14.12 mmol) was added at room temperature and reaction stirred overnight. Solvent was removed under reduced pressure to afford the adduct product (99%) as an oil. MS m/z 342.4 (M++1) .
