A solution of 6.0 g (27.5 mmol) of N′-(2-cyano-4-nitrophenyl)-N,N-dimethylformamidine, 33.9 g (41.8 ml, 412.4 mmol) of cyclohexene, and 0.6 g of 10% Pd/C in 360 ml of methanol was refluxed for 4 hrs. The hot mixture was filtered through Celite. Solvent was removed and the residue was recrystallized from chloroform-carbon tetrachloride giving 4.9 g (95%) of the tidle compound as a light gray crystalline solid. mass spectrum (m/e): 188.9 (M+H, electrospray).
