Procedure
A solution of 15 g of (2-chloro-3-nitropyridin-4-yl)acetonitrile and 1.1 equivalents of N-benzyl-piperazine is heated for 10 minutes, at 80° C., under a stream of argon, and then concentrated under reduced pressure. Chromatography on silica gel (dichloromethane/methanol: 100/0 to 95/5) enables the expected product to be isolated.
