Procedure

1 mmol of N-[2-({2-[(6-amino-5-nitro(2-pyridyl))amino]ethyl}amino)-4-(2,4-dichlorophenyl)pyrimidin-5-yl]acetamide and 2 mmol of Lawesson's reagent were stirred in 2 ml of DME at 80° C. The reaction mixture was concentrated in vacuo and diluted with water and ethyl acetate. The solution was extracted three times with ethyl acetate, dried over sodium sulfate, and purified by column chromatography eluting with 5-10% methanol/methylene chloride to obtain 1-{[2-({2-[(6-amino-5-nitro(2-pyridyl))-amino]ethyl}amino)-4-(2,4-dichlorophenyl)pyrimidin-5-yl]amino}ethane-1-thione.
