Dimethyl Sulfoxide → 6-{[2-({2-(Morpholin-4-ylmethyl)-7-[4-(trifluoromethyl)phenyl][1,2,4]triazolo[1,5-c]pyrimidin-5-yl}amino)ethyl]amino}pyridine-3-carbonitrile

Participants

Reaction Steps

300 mg (0.75 mmol) of 5-chloro-2-(morpholin-4-ylmethyl)-7-[4-(trifluoromethyl)-phenyl][1,2,4]triazolo[1,5-c]pyrimidine (Example 151A) and 180 mg (0.91 mmol) of 6-[(2-aminoethyl)amino]pyridine-3-carbonitrile (Example 13A) are introduced into DMSO (4 ml), 0.79 ml (4.5 mmol) of DIEA is added, and the reaction solution is irradiated in a microwave reactor at 140° C. for 30 min. The reaction mixture is diluted with ethyl acetate, and the organic phase is washed with saturated sodium bicarbonate solution, ammonium chloride solution and saturated sodium chloride solution, dried and concentrated. The residue is taken up in acetonitrile (4 ml), and the solid which precipitates is filtered off and dried. 300 mg (76% of theory) of the product are obtained as a solid.
