Procedure

To a mixture of 4-(4-(4-bromo-2,6-dimethylphenylthio)-6-methyl-5-nitropyrimidin-2-ylamino)benzonitrile (50 mmol) in DMF (300 ml) is added tert-butoxybis (dimethylamino) methane (60 mmol) over 15 minutes. The mixture is stirred at room temperature overnight. DMF is partially removed. The residue is washed with water and extracted with ethyl acetate (×3). The combined organic layers are washed with brine, dried (MgSO4) and concentrated to dryness to give the desired product which is used in next step without further purification.
