Versuchsvorschrift

The process is carried out according to the method described in step 5.1, using 5.4 g (28.64 mmol) of 2-chloro-4-methoxy-5-nitropyridine (WO 03/080610) and 4.53 g (63 mmol) of pyrrolidine. The product obtained is, in this case, purified by silica column chromatography, elution being carried out with a mixture of heptane and ethyl acetate. 3 g of the expected product are thus isolated.
