Procedure

The amine (Example 37A) (300 mg, 0.46 mmol), 2-chloro-5-cyanopyridine (129 mg, 0.93 mmol) and N,N-diisopropylethylamine (600 mg, 4.6 mmol) are introduced into DMSO (6 ml), and heated at 150° C. in a microwave oven for 30 min. The reaction mixture is poured into water and extracted with ethyl acetate (3×25 ml). The combined organic phases are washed with saturated aqueous sodium chloride solution, dried over magnesium sulphate and concentrated. The residue is taken up in acetonitrile, and the product precipitates and is washed with acetonitrile and dried. 87 mg (41% of theory) of the product are obtained as a solid.
