Procedure

A suspension of 0.5 g (2.9 mmol) of 6-chloro-3-nitro-2-picoline, of 0.73 ml (8.69 mmol) of pyrrolidine and of 0.8 g (5.79 mmol) of potassium carbonate is heated at 110° C. for 2 hours. The reaction mixture is subsequently concentrated under reduced pressure and then poured into 100 ml of water. A solid is recovered by filtration and is dried so as to obtain 0.55 g of the expected product in the form of a yellow solid which will be used as it is in the rest of the synthesis.
