Versuchsvorschrift

To a suspension of 730 mg of NaH in a mixture of DMF/DMSO (25/2.5 ml) is added drop-wise at 0° C., 2.53 g (12.69 mmol) of 2-(iso-propylsulfonyl)benzenamine in DMF/DMSO (10 ml, ratio 9/1). The solution is stirred 30 minutes at 0° C. and 4.11 g (25.3 mmol, 2 eq.) of 2,4-dichloro-5-methylpyrimidine diluted in 10 ml of DMF/DMSO (ratio: 9/1) is added dropwise. The solution is warmed-up to room temperature and stirred overnight. After work-up, the crude product is directly crystallized from cold CH3CN in several batches to afford 2-chloro-N-(2-(iso-propylsulfonyl)phenyl)-5-methylpyrimidin-4-amine as pale creamy colored crystals: ESMS m/z 326.1 (M+H+).
