Reaction Steps

In acetonitrile (3 ml) was dissolved 200 mg (0.56 mmol) of 4-cyano-5-methyl-4-(5-cyano-2-thienyl)hexyl iodide. To the mixture were added 78.0 μl (0.56 mmol) of triethylamine and 178 mg (0.76 mmol) of 1-[3-(5-cyano-2-thieny)propyl]piperazine, followed by stirring at 55° C. After 5 hours, the reaction solution was concentrated, and the residue was subjected to Cromatorex NH silica gel (ethyl acetate/hexane=1/2), to give 243 mg (0.52 mmol, 92.8%) of the title compound as a yellow syrup.
