Reference of 3222-56-8, Adding some certain compound to certain chemical reactions, such as: 3222-56-8, name is 2-Methylnicotinic acid,molecular formula is C7H7NO2, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 3222-56-8.
To a solution of acid 2-methylpyridin-3-carboxylic (0.40 g, 2.90 mmol, 1 eq) in DMF dry (4.0 mL), ammonium chloride (0.93 g, 17.50 mmol, 6 eq), HOBt (0.57 g, 4.20 mmol, 1.44 eq), EDCI (0.81 g, 4.20 mmol, 1.44 eq) and N-methylmorpholine (0.46 mL, 4.20 mmol, 1.44 eq) were subsequently added. The reaction was stirred at room temperature, under nitrogen for 2.5 h. Evaporation of the solvent gave a residue which was purified by column chromatography (neutral alumine oxide, Brockmann grade III) using EtOAc as eluant to give 9 as white solid after crystallization with EtOAc (0.27 g, 69%). Mp. 163-166 C. 1H NMR (300 MHz, CD3OD) delta 8.45 (dd, J = 4.9/1.8 Hz, 1-H), 7.83 (dd, J = 7.6/1.5 Hz, 1-H), 7.30 (dd, J = 7.6/4.9 Hz, 1-H), 2.61 (s, 3-H); 13C NMR (75 MHz, CD3OD) delta 172.0, 155.4, 149.2, 135.7, 132.2, 121.2, 21.2; GC-MS m/z 136 (M)+; IR (KBr) 2768, 2389, 1926, 1692, 1448, 1365 cm-1. Anal. Calcd for C7H8N2O: C, 61.75; H, 5.92; N, 20.58. Found: C, 61.91; H, 6.20; N, 20.10.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 3222-56-8, 2-Methylnicotinic acid, other downstream synthetic routes, hurry up and to see.
