Procedure

5 g (32.03 mmol) of 2-fluoro-5-nitroaniline and 4.9 ml (48.04 mmol) of 2-methylpyrrolidine (racemic) are placed in a screw reactor. The reactor is closed and the mixture is heated at 100° C. for 5 h. After cooling, the mixture is taken up with 100 ml of water and 100 ml of dichloromethane. The organic phase is separated, washed with 50 ml of a saturated solution of sodium chloride, dried over magnesium sulphate and then concentrated under reduced pressure. The resulting product is used as it is in the subsequent reaction.
