Reaction Steps

60 mg (0.21 mmol) of 2-chloro-6-(2,4-dichlorophenyl)pyridine-3-carbonitrile, 63 mg (0.25 mmol) of 6-(piperidin-3-ylamino)pyridine-3-carbonitrile hydrochloride (Example 10A) and 0.184 ml (1.06 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.
