Diisopropylethylamine → 6-{[2-({7-(2,4-Dichlorophenyl)-2-[1-(propan-2-yl)piperidin-4-yl][1,2,4]triazolo[1,5-c]pyrimidin-5-yl}amino)ethyl]amino}pyridine-3-carbonitrile

Reaction Steps

50 mg (0.12 mmol) of 5-chloro-7-(2,4-dichlorophenyl)-2-[1-(propan-2-yl)piperidin-4-yl][1,2,4]-triazolo[1,5-c]pyrimidine hydrochloride (Example 40A), 28 mg (0.14 mmol) of 6-[(2-aminoethyl)-amino]pyridine-3-carbonitrile dihydrochloride (Example 2A) and 0.125 ml (3.5 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), 48 mg (74% of theory) of the product as a solid.
