Related Products of 6937-03-7, 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. 6937-03-7, name is Methyl 2-aminoisonicotinate. A new synthetic method of this compound is introduced below.
(2-Amino-pyridin-4-yl)-methanol (2-4) 2-Amino-isonicotinic acid methyl ester (6.0 g, 39.4 mmol) was dissolved in 80 mL anhydrous THF in a flame dried round bottom flask under nitrogen gas. The solution was cooled to -45° C. and LAH (39.4 mL, 1M in THF) was added slowly. The reaction was allowed to warm to 0° C. and was quenched by the addition of 15 mL of 1M NaOH (aq). The solution was filtered and the solid was washed with THF. The filtrate was concentrated to afford the pure product. 1H NMR (DMSO-d6) delta7.79 (d, 1H, J=5.2 Hz), 6.41 (s, 1H), 6.38 (d, 1H, J=5.9 Hz), 5.79 (bs, 2H), 5.19 (t, 2H, J=5.7), 4.35 (d, 2H, J=5.6 Hz).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,6937-03-7, Methyl 2-aminoisonicotinate, and friends who are interested can also refer to it.
