Participants

Conditions

Temperature: 130 °C

Procedure

120 mg (0.23 mmol) of ethyl{4-[5-chloro-7-(2,4-dichlorophenyl)[1,2,4]triazolo[1,5-c]pyrimidin-2-yl]piperidin-1-yl}acetate (Example 55A), 54.9 mg (0.28 mmol) of 6-[(2-aminoethyl)amino]-pyridine-3-carbonitrile dihydrochloride (Example 2A) and 0.24 ml (1.38 mmol) of N,N-diisopropylethylamine were initially charged in 2.33 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), 113 mg (77% of theory) of the product as a solid.
