Related Products of 872355-63-0, 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.872355-63-0, name is Methyl 1H-pyrrolo[3,2-b]pyridine-5-carboxylate, molecular formula is C9H8N2O2, molecular weight is 176.172, as common compound, the synthetic route is as follows.
A solution of methyl 1 H-pyrrolo[3,2-b]pyridine-5-carboxylate (Adesis Inc., New Castle, Delaware) (1.0 g, 5.68 mmol) and di-te/t-butyl dicarbonate (1.75 g, 7.95 mmol) in methanol (30 ml.) was passed through an H-cube hydrogenation apparatus equipped with a 10%Pd/C cartrige at 80 degrees Celsius and 80 bar 1.0 mL/minute. The effluent was then passed through the H-cube apparatus three additional times. The crude material was concentrated and the residue was purified by silica gel chromatography, eluting with a gradient mixture of 50% to 90% ethyl acetate to heptane to give 230 mg of methyl 2,3-dihydro-1 H-pyrrolo[3,2-b]pyridine-5-carboxylate and 300 mg of 1-te/t-butyl 5- methyl 2,3-dihydro-1 H-pyrrolo[3,2-b]pyridine-1 ,5-dicarboxylate.Methyl 2,3-dihydro-1 H-pyrrolo[3,2-b]pyridine-5-carboxylate:_1H NMR(deuterochloroform) delta 7.77 (d, J = 8.2 Hz, 1 H), 6.67 (d, J = 8.2 Hz, 1 H), 4.42 (br. s., 1 H), 3.88 (s, 3H), 3.69 (td, J = 8.6, 1.5 Hz, 2H), 3.17 (t, J = 8.7 Hz, 2H).1-te/t-Butyl 5-methyl 2,3-dihydro-1 H-pyrrolo[3,2-b]pyridine-1 ,5-dicarboxylate: 1H NMR (deuteurochloroform) delta 7.92 (d, J = 8.2 Hz, 2H), 4.00 (t, J = 8.9 Hz, 2H), 3.91 (s, 3H), 3.25 (t, J = 1.0 Hz, 2H), 1.52 (br. s., 9H).
The chemical industry reduces the impact on the environment during synthesis 872355-63-0, I believe this compound will play a more active role in future production and life.
