4-Methylpyrimidin-5-amine Use and Manufacturing
To a solution of the reactant (109 mg, 1.0 mmol) in toluene (1.5 mL) was added acetic anhydride (0.2 mL, 2.10 mmol), acetic acid (0.2 mL, 3.5 mmol) followed by potassium acetate (196 mg, 2.0 mmol). The mixture was heated to reflux and isopentyl nitrire (0.168 mL, 1.25 mmol) in toluene (0.3 mL) was added. After 2 hours, the mixture was poured into water (20 mL). The solution was made basic by addition of Na2C03 solid. The solution was extracted with ethyl acetate (2x50 mL) and the combined organic extracts were washed with brine (50 mL), dried over magnesium sulfate and concentrated in vacuo. The residue was purified by silica gel chromatography (eluant:petroleum ether: ethyl acetate = 1 :2) to afford product product (32 mg, 0.266 mmol, Yield=27%) as yellow solid. 1H NMR (400 MHz, d6-DMSO) 5(ppm): 13.91 (1H, br), 9.35 (1H, s), 9.04 (1H, s), 8.45 (1H, s).In an oven-dried 500 mL two-necked round-bottomed flask 1-bromo-2-nitrobenzene (18.33 g, 91 mmol),
