2-CYANO-4-PYRIDINE CARBOXYLIC ACID METHYL ESTER Uses

  1. Tobinostat is used for the treatment of chronic hyperuricemia in gout. Compared with the traditional drug allopurinol (purine analog), it will not affect the metabolism of purine and pyridine and the activity of its enzymes, and its effect of reducing uric acid is stronger. High-dose repeated administration is not required, and the safety is better, and methyl 2-cyano-4-pyridine carboxylate is an important raw material for synthesizing tobicistat.
  2. Methyl 2-cyano-4-pyridinecarboxylate can be used in the synthesis of various pharmaceuticals and bioactive compounds, such as tetrasubstituted imidazolines, as potent and selective neuropeptide Y (NPY) Y5 receptor antagonists.

Preparation of Methyl 2-cyano-4-Pyridinecarboxylate

To a 250ml there-necked flask, add methylisonicotinic acid-N-oxide (15.31g, 0.1mol) and 200ml of acetonitrile and stir to dissolve completely, add triethylamine (15g, 0.15mol), trimethylsilicon cyanide (29.76g) , 0.3mmol), nitrogen protection reflux reaction for 20 hours, TLC detection reaction ends. The solvent was evaporated to dryness under reduced pressure, and the residue was subjected to silica gel column chromatography, eluted with dichloromethane-methanol (50:1), to obtain a yield of 13.48 g of white crystals, 83.14%. 1H NMR (600 MHz, DMSO-d6, δppm): 4.03(s,3H,), 8.11(d,1H,), 7.76(s,1H), 8.26(s,1H), 8.89(d,1H).

Purity Detection of Methyl 2-cyano-4-Pyridinecarboxylate

The impurities produced during the synthesis of methyl 2-cyano-4-pyridinecarboxylate mainly include methyl isonicotinate and methylisonicotinic acid N-oxide.

Methyl 2-cyano-4-pyridinecarboxylate and main impurity methyl isonicotinate are similar in polarity, CN201610560075.4 provides a kind of isocratic elution to realize methyl 2-cyano-4-pyridinecarboxylate and phase The adjacent impurity peaks can be completely separated, and the method with good peak shape can realize the accurate analysis of the content of methyl 2-cyano-4-pyridinecarboxylate. A high-performance liquid chromatography purity detection method for complete separation of methyl 2-cyano-4-pyridine carboxylate and its main impurities involved in the present invention comprises the following steps:

a. Preparation of the test solution: take methyl 2-cyano-4-pyridinecarboxylate, dissolve it with mobile phase or methanol, and prepare a solution with a concentration of 0.5mg/ml to 1.2mg/ml as the test solution .

b. Preparation of impurity reference solution: take methyl isonicotinate and methylisonicotinic acid N-oxide, dissolve with mobile phase or methanol, and prepare a solution with a concentration of 0.5mg/ml ~ 1.2mg/ml as impurities reference solution.

c. Use high performance liquid chromatography to detect the test solution and the impurity reference solution respectively. The detection conditions are: the chromatographic column is a C18 column; the mobile phase is methanol-buffer salt, and the volume ratio of methanol to the buffer solution is 10%: 90%~90%: 10%; the injection volume is 20ul, the flow rate is 0.5ml/min~1.5ml/min; the column temperature is 10℃~40℃; the detection wavelength is 200nm~300mn.

d. Calculate the peak areas of methyl isonicotinate and methylisonicotinic acid N-oxide according to the peak area normalization method.
