Synthetic Route of 917364-11-5, 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.917364-11-5, name is 5,6,7,8-Tetrahydroimidazo[1,2-a]pyridine-2-carboxylic acid, molecular formula is C8H10N2O2, molecular weight is 166.18, as common compound, the synthetic route is as follows.
Example 12 (S)-N-(1-(3-(3-Chloro-4-cyano-5-fluorophenyl)-1H-pyrazol-1-yl)propan-2-yl)-5,6,7,8-tetrahydroimidazo[1,2-a]pyridine-2-carboxamide The title compound was prepared using the procedure described in Example 3(h) starting from 5,6,7,8-tetrahydroimidazo[1,2-a]pyridine-2-carboxylic acid (2.58 mmol, 428 mg) and (S)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chloro-6-fluoro-benzonitrile (1.717 mmol, 479 mg). DMF (10 ml) was used as the solvent. The reaction mixture was diluted with water and extracted three times with DCM. The combined organics were washed twice with water. The organic phase was evaporated. The crude product was purified by flash chromatography. 515 mg of the title compound was obtained. 1H-NMR (400 MHz, DMSO-d6): delta 1.07 (d, 3H), 1.78-1.94 (m, 4H), 2.76 (t, 2H), 3.95 (t, 2H), 4.24-4.31 (m, 1H), 4.33-4.46 (m, 2H), 7.01 (d, 1H), 7.43 (s, 1H), 7.84 (d, 1H), 7.90-7.95 (m, 1H), 8.00 (s, 1H), 8.08 (d, 1H).
The chemical industry reduces the impact on the environment during synthesis 917364-11-5, I believe this compound will play a more active role in future production and life.
