3-Amino-1,2-propanediol → 3-[(3-Nitropyridin-4-yl)amino]propane-1,2-diol

Participants

Reaction Steps

A solution of 4-chloro-3-nitropyridine (1.1 g, 6.94 mmol) and 3-amino-1,2-propanediol (1.22 g, 13.4 mmol) in isopropanol (50 ml) was stirred at 20°-25° C. for 20 hours and then concentrated under reduced pressure. Flash chromatography of the residue over silica gel and elution with 10% MeOH-90% CHCl3 gave pure 4-(2,3-dihydroxy-1-propylamino)-3-nitropyridine (500 mg, 33.8%). An analytically pure sample, m.p. 131°-35° C., was obtained upon recrystallization from MeOH-EtOAc-hexane.
