YieldReaction ConditionsOperation in experiment
With trichlorophosphate; for 1h;Heating / reflux; lambda/-{4-[(2-amino-6-methyl-4-pyrimidinyl)amino]phenyl}-5-nitro- 2-pyridinecarboxamide 20. 5-Nitropyridine-2-carboxylic acid 18 (1.06g, 6.31 mmol) was refluxed in POCI3 (10 ml_) for 1 h. (clear solution obtained), cooled to 20 0C and excess POCb was removed under vacuum. The resulting residue was dissolved in 1 ,4-dioxane ((20 ml_) and added slowly to a suspension of 17 (1.44 g, 5.72 mmol)and lambda/,lambda/-diethylaniline (2.0 mL, 12.62 mmol) in 1 ,4-dioane (20 mL). The reaction mixture was stirred at 20 0C for 3 days. The resulting white precipitate was filtered and washed with more 1 ,4-dioxane. The solid was stirred in aqueous NH3 (20 mL) and the resulting red precipitate was filtered, washed with water and recrystallized from MeOH to give 20 (708 mg, 31 %); mp (MeOH) >290C; 1H NMR ([(CDa)2SO] delta 10.74 (1 H, NH), 9.43 (dd, J = 2.6, 0.5 Hz, 1 H, H-6), 8.96 (s, 1 H, NH), 8.81(dd, J = 8.6, 2.6 Hz, 1 H, H-4), 8.38 (dd, J = 8.6, 0.6 Hz, 1 H, H-3), 7.81 (d, J = 9.0 Hz, 2 H, H-2' H-6'), 7.70 (d, J = 9.1 Hz, 2 H, H-3', 5'), 6. 09 (s, 2 H, NH2), 5.87 (s, 1 H, H-5"), 2.09 (s, 3 H, CH3); HRMS (FAB+) calc. for C17H16N7O3 (M+1) m/z 366.1315, found 366.1314; Anal, calc. for C17H15N7O3.0.25 MeOH: C, 55.5; H, 4.4: N, 26.3; found, C, 55.7; H, 4.5; N, 26.2%.
