Temperature130 °C

Reaction Steps

50 mg (0.10 mmol) of 5-chloro-2-[1-(cyclopropylmethyl)piperidin-4-yl]-7-(2,4-dichlorophenyl)-[1,2,4]triazolo[1,5-c]pyrimidine (Example 47A), 25 mg (0.12 mmol) of 6-[(2-aminoethyl)amino]-pyridin-3-carbonitrile hydrochloride (Example 2A) and 0.110 ml (0.6 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), 22 mg (38% of theory) of the product as a solid.
