Quality Control of Imidazo[1,2-a]pyridine-3-carboxylic acid

General procedure: To a solution of 2-methyl-3-phenyl-4,5,6,7-tetrahydro-2H-pyrazolo[3,4-c]pyridine, Intermediate 1, (150 mg, 0.7 mmol) in dichloromethane (DCM) (5.0 mL) was added HATU (348 mg, 0.91 mmol), followed by DIPEA (0.6 mL, 3.5 mmol) and 1-naphthoic acid (222 mg, 1.3 mmol), and the mixture stirred at room temperature for 1 h. The reaction mixture was diluted with water and the aqueous layer extracted with DCM (*2). The combined organics were washed with brine, dried over Na2SO4, filtered, and concentrated in vacuo. The crude residue was purified by reverse-phase HPLC (Method A) to afford the title compound as a white solid (94 mg, 36% yield). MS (ESI): mass calcd. for C24H21N3O, 367.1; m/z found, 368.1 [M+H]+. 1H NMR (400 MHz, Methanol-d4) delta 8.12-7.93 (m, 2H), 7.89-7.74 (m, 1H), 7.67-7.35 (m, 9H), 5.20-4.92 (m, 2H), 4.46-4.22 (m, 1H), 4.13-3.98 (m, 0.3H), 3.76 (d, J=54.9 Hz, 3H), 3.52-3.41 (m, 1H), 2.93-2.75 (m, 0.7H), 2.57-2.30 (m, 1H).

The synthetic route of 6200-60-8 has been constantly updated, and we look forward to future research findings.

Here is a downstream synthesis route of the compound 6200-60-8.

To a solution of imidazo[1,2-a] pyridine-3-carboxylic acid (250 mg) in DMF (7 mL), EDCI (443 mg, 1.5 equiv.), HOBt (312 mg, 1.5 equiv.), DIPEA (805 muL, 3.0 equiv.) and compound 73 (404 mg, 1.0 equiv.) were added. The resulting mixture was stirred at R.T. overnight. The reaction mixture was diluted with AcOEt (15 mL), washed with HCl 1M (2*10 mL) and water (2*10 mL). Combined aqueous layers were saturated with NaHCO3 and extracted with AcOEt (2*10 mL). The combined organic layers were washed with brine, dried over MgSO4 and concentrated under reduced pressure. Purification by flash-chromatography (MeOH 2% to 5% in CH2Cl2) followed by preparative HPLC afforded the product as a white solid (9.3 mg, yield <5%). 1H-NMR (400 MHz, DMSO): 1.11-1.79 (m, 13H, 5*CH2 + CH3); 3.33 (q, J 7.0 Hz, 2H, N-CH2); 6.81 (dd, J 1.9 Hz, J 8.1 Hz, 1H, Ar); 6.90 (d, J 2.0 Hz, 1H, Ar); 7.20 (m, 1H, Ar); 7.55 (m, 1H, Ar); 7.75-7.78 (m, 2H, Ar); 8.56 (s, 1H, Ar); 9.36 (bs, 1H, NH); 9.47 (m, 1H, Ar).
