The mixture of 4-(2-(3-methyl-1H-1,2,4-triazol-1-yl)-5-nitrophenoxy)butan-1-amine, 2 TFA (46.6 mg, 0.090 mmol), 2,4-dichloro-8-(4-fluorophenyl)-6-methyl-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine (20 mg, 0.064 mmol) and DIEA (55.9 μL, 0.320 mmol) in acetonitrile (320 μL) and 2 drops of MeOH was stirred at rt overnight. The crude product was purified by Prep-HPLC to obtain 2-chloro-8-(4-fluorophenyl)-6-methyl-N-(4-(2-(3-methyl-1H-1,2,4-triazol-1-yl)-5-nitrophenoxy)butyl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidin-4-amine, 2 TFA (43.6 mg, 82% yield).
