Reaction Steps

50 mg (0.13 mmol) of 5-chloro-7-(2,4-dichlorophenyl)-2-(1-methylpiperidin-4-yl)[1,2,4]triazolo-[1,5-c]pyrimidine hydrochloride (Example 49A), 30 mg (0.15 mmol) of 6-[(2-aminoethyl)amino]pyridin-3-carbonitrile hydrochloride (Example 2A) and 0.13 ml (0.76 mmol) of N,N-diisopropylethylamine were initially charged in 1.5 ml of DMSO. The mixture was heated in the microwave at 130° C. for 30 min. This gave, after purification of the crude product by preparative HPLC (Method 11), 25 mg (37% of theory) of the product as a solid.
