Reaction Steps

55 mg (0.19 mmol) of 2-chloro-6-(2,4-dichlorophenyl)pyridine-3-carbonitrile, 60.9 mg (0.23 mmol) of 2-amino-6-(piperidin-3-ylamino)pyridine-3-carbonitrile hydrochloride (Example 11A) and 0.169 ml (0.97 mmol) of N,N-diisopropylethylamine were initially charged in 2 ml of DMSO. The mixture was heated at 120° C. in a microwave for 30 min. The crude product was purified by means of preparative HPLC (method 13). 30 mg (33% of theory) of the product were obtained in solid form.
