Diisopropylethylamine → (4-(6-Amino-3-(2-methyl-3-nitrophenyl)-1,2,4-triazin-5-ylamino)phenyl)(morpholino)methanone

Participants

Reaction Steps

A mixture of 5-chloro-3-(2-methyl-3-nitrophenyl)-1,2,4-triazin-6-amine (1.05 g, 3.95 mmol), (4-aminophenyl)(morpholino)methanone (1.630 g, 7.90 mmol), and N,N-diisopropylethylamine (1.243 mL, 7.11 mmol) in 1,4-dioxane (60 mL) was heated at reflux for 2 days. The volatiles were removed under vacuum. To the residue was added water (60 mL). The precipitating material was collected by suction filtration. The filter cake was purified by ISCO (120 g silica gel, solid loading, 3-8% MeOH/CH2Cl2) to provide the desired product, (4-(6-amino-3-(2-methyl-3-nitrophenyl)-1,2,4-triazin-5-ylamino)phenyl)(morpholino)methanone (0.595 g, 1.339 mmol, 33.9% yield), as a yellow solid.
