Participants

Reaction Steps

3.4 g of methyl chloronicotinate, 5.5 g of potassium carbonate, 3.3 g of 4-pyridylpiperazine and a spatula tipful of 18-crown-6 were heated at 100° C. for 5 h in 75 ml of DMF and then stirred at room temperature for 60 h. The excess potassium carbonate was filtered off, the filtrate was concentrated and the residue was partitioned between water and ethyl acetate.
