Diisopropylethylamine → Ethyl 5-({2-[(5-cyanopyridin-2-yl)amino]ethyl}amino)-7-[4-(trifluoromethyl)phenyl][1,2,4]-triazolo[1,5-c]pyrimidine-2-carboxylate

Participants

Reaction Steps

200 mg (0.52 mmol) of ethyl 5-chloro-7-(4-trifluoromethylphenyl)[1,2,4]triazolo[1,5-c]pyrimidine-2-carboxylate (Example 149A) and 123 mg (0.62 mmol) of 6-[(2-aminoethyl)amino]pyridine-3-carbonitrile (Example 13A) are introduced into DMSO (2 ml), 0.54 ml (3.1 mmol) of DIEA is added, and the reaction solution is irradiated in a microwave reactor at 90° C. for 30 min. The reaction mixture is purified by preparative HPLC. 98 mg (38% of theory) of the product are obtained as a solid.
