120 mg (0.23 mmol) of ethyl{4-[5-chlor-7-(2,4-dichlorophenyl)[1,2,4]triazolo[1,5-c]pyrimidin-2-yl]piperidin-1-yl}acetate (Example 55A), 78.7 mg (0.28 mmol) of 1-{2-amino-6-[(2-aminoethyl)-amino]pyridin-3-yl}-2,2,2-trifluoroethanone hydrochloride (Example 13A) and 0.24 ml (1.38 mmol) of N,N-diisopropylethylamine were initially charged in 1 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), 141 mg (90% of theory) of the product as a solid.
