Procedure

2-[(6-Amino-5-nitropyridin-2-yl)amino]ethanol (Example 48A) is introduced into DMF (3 ml) at 0° C., and sodium hydride (60% oil dispersion, 15 mg, 0.4 mmol) is added. The mixture is stirred at 0° C. for 10 min. 5-Chloro-7-(2,4-dichlorophenyl)imidazo[1,2-c]pyrimidine (Example 6A) (125 mg, 0.4 mmol) in DMF (1 ml) is added dropwise, and the reaction mixture is stirred at RT for 12 h. Glacial acetic acid (200 μl) is added, and the reaction mixture is poured into water and extracted with ethyl acetate (3×50 ml). The combined organic phases are washed with saturated aqueous sodium chloride solution, dried over magnesium sulphate and concentrated. The residue is precipitated from acetonitrile, filtered off, washed with acetonitrile and dried. 36 mg (18% of theory) of product are obtained as a solid.
