The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 872355-64-1, name is 1H-Pyrrolo[3,2-b]pyridine-5-carboxylic acid. This compound has unique chemical properties. The synthetic route is as follows. category: pyridine-derivatives

lH-pyrrolo[3,2-b]pyridine-5-carboxylic acid (0.49 g) and l-[l-(4-fluoro-phenyl)- ethyl]-2S,5R-dimethyl-piperazine (0.67 g) were dissolved in dry DMF (5 mL) and TBTU (0.97 g) was added followed by triethylamine (1.3 mL). The mixture was stirred overnight, whereupon it was poured into water and the solid thus separated was filtered and dried. The crude material was purified by flash chromatography using 20 % methanol : 80 % dichloromethane as a solvent (Yield: 0.49 g, Rf: 0.74 min, Condition B, M+H+: 367).

With the rapid development of chemical substances, we look forward to future research findings about 872355-64-1.

Preparation of compound 9a: 3-iodo-lH-pyrrolo[3,2-b]pyridine-5-carboxylic acidTo a solution of lH-pyrrolo[3,2-b]pyridine-5-carboxylic acid (0.400 g, 2.467 mmol, Adesis, New Castle, DE) in DMF (4.9 mL) was added I2 (0.626 g, 2.467 mmol) and KOH (0.346 g, 6.17 mmol). The mixture was stirred at RT for 1 h. The mixture was poured into ice and H20 (30 mL) containing sodium bisulfite (0.257 g, 2.467 mmol). The reaction was acidified with 5 M HCl. A yellow solid precipitated out and was collected by filtration, washed with H20 and dried overnight in a vacuum oven to give 3-iodo-lH- pyrrolo[3,2-b]pyridine-5-carboxylic acid (0.516 g, 1.791 mmol, 72.6 % ). MS (ESI, pos. ion) m/z: 289.0 (M+l). .H NMR (400 MHz, DMSO-d6) delta ppm 7.91 (2 H, s), 8.01 (1 H, d, J=2.74 Hz), 12.03 – 12.11 (1 H, m).
