Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 113293-71-3, name is (6-Aminopyridin-3-yl)methanol. A new synthetic method of this compound is introduced below., Quality Control of (6-Aminopyridin-3-yl)methanol

General procedure: Triphenylphosphine (TPP) (280 mg, 1.07 mmol) was added in portions to a freshly prepared solution of the designated alcohol (1.0 mmol) and the specified phenolic acid (1.0 mmol equivalent) in anhydrous THF (3.5 mL) at 0 C. Diisopropylazodicarboxylate (DIAD) (208 mL, 1.0 mmol) was then added dropwise to the mixture. The reaction mixture was stirred at 0 C for 30 min. The mixture was then warmed and stirring was continued for 48 h at rt [19]. Reactions were monitored till completion by TLC. The reaction mixture was then worked up by removal of the solvent under reduced pressure, saturated solution of NaHCO3 (10 mL) was added, and then the mixture was extracted with EtOAc (3 x 20 mL). The combined organic layers were washed with brine, dried over anhydrous Na2SO4, filtered, and the filtrate was evaporated under reduced pressure to dryness. The crude product was collected and purified by column chromatography(CC) on Sephadex LH-20 using isocratic CH2Cl2 followed by chromatography on Si gel 60 using n-hexane-EtOAc system, gradient elution, to afford 5-9 and 13-47 (Supplementary Information).

Electric Literature of 113293-71-3, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.113293-71-3, name is (6-Aminopyridin-3-yl)methanol, molecular formula is C6H8N2O, molecular weight is 124.14, as common compound, the synthetic route is as follows.

To a stirring of (6-aminopyridin-3-yl)methanol (1.24 mg, 10.0 mmol) and ethyl 2-chloro-3-hydroxyacrylate, potassium salt (29) (3.76 g, 20.0 mmol) in EtOH (10 mL) at room temperature was added conc sulfuric acid (10.0 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. 1H NMR (400 MHz, d6-DMSO) delta 9.16 (d, J=6.8 Hz, 1H), 8.26 (s, 1H), 7.67 (s, 1H), 7.19 (dd, J=1.6, 6.8 Hz, 1H), 5.57 (t, J=6.4 Hz, 1H), 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)+.
