The downstream synthesis method of this compound is introduced below.
A mixture of 5-chloro-2-pyridinecarboxylic acid (1.0 g, 6.35 mmol) and cone. H2SO4 (0.1 ml) was heated in EtOH (10 ml) at 80 0C for 16 hours. After cooling and concentrating at reduced pressure, the residue was dissolved in EtOAc (50 ml), washed with saturated NaHCO3 (25 ml) and brine (25 ml), dried (MgSO4), filtered and re-concentrated at reduced pressure giving the title compound (990 mg, 84%).LCMS data: Calculated MH+ (186); Found 98% (MH+) m/z 186, Rt = 1.13 min. NMR data: 1H NMR (250 MHz, CDCl3) delta ppm 8.63 – 8.76 (1 H, m), 8.10 (1 H, d, J=8.4 Hz), 7.82 (1 H, dd, J=8.5, 2.4 Hz), 4.49 (2 H, q, J=7.2 Hz), 1.45 (3 H, t, J=7.2 Hz).
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 86873-60-1, 5-Chloro-2-picolinic acid.
