This compound has unique chemical properties. The synthetic route is as follows. Computed Properties of C6H8N2O
To a stirring suspension of (6-aminopyridin-3-yl)methanol (1 .24 mg, 10.0 mmol) and ethyl 2-chloro-3-hydroxyacrylate, potassium salt (29) (3.76 g, 20.0mmol) in EtOH (10 mL) at room temperature was added cone sulfuric acid (1 0.0 mmol) dropwise. The reaction mixture was stirred at room temperature for 15 minutes and pyridine (0.92 g, 12.0 mmol) was added. The resulting mixture was heated at 85 C overnight. The reaction was cooled to room temperature and the solvent was concentrated. The residue was taken in water and the solution was adjusted to pH 8 with saturated sodium bicarbonate. The crude product was extracted with ethyl acetate. The organic layer was washed with brine and dried over anhydrous sodium sulfate. The crude product ethyl 6- (hydroxymethyl)imidazo[1 ,2-a]pyridine-3-carboxylate (59) was purified by silica chromatography. 1 H NMR (400MHz, c/6-DMSO) delta 9.16 (d, J = 6.8 Hz, 1 H), 8.26 (s, 1 H), 7.67 (s, 1 H), 7.19 (dd, J = 1 .6, 6.8 Hz, 1 H), 5.57 (t, J = 6.4 Hz, 1 H), 4.63 (d, J = 6.0, 2H), 4.36 (q, J = 7.2 Hz, 2H), 1 .35 (t, J = 6.8 Hz, 3H). MS m/z 221 .1 (M+1 ) +.
