Simple exploration of 5-Nitro-1H-pyrrolo[2,3-b]pyridine

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 101083-92-5, 5-Nitro-1H-pyrrolo[2,3-b]pyridine, other downstream synthetic routes, hurry up and to see.

Synthetic Route of 101083-92-5 ,Some common heterocyclic compound, 101083-92-5, molecular formula is C7H5N3O2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.

EXAMPLE 43; [0221] This example illustrates a preparation of 6-methoxy-2-(l-methyl-lH-pyrrolo[2,3- delta]pyridin-5-yl)isoindolin-l-one in an embodiment of the invention.; Step A: Synthesis of l-methyl-5-nitro-7-azaindole,; [0222] A solution of 5-nitro-7-azaindole (0.195 g, 1.2 mmol) in DMF (10 mL) was treated with NaH (60%, 0.057 g, 1.44 mmol), followed by iodomethane (0.204 g, 1.44 mmol). The reaction mixture was stirred at room temperature for 4.5 h, then poured into water (200 mL) and extracted with dichloromethane (3 chi100 mL). The combined organic layer was washed with brine (100 mL), dried over sodium sulfate, and concentrated. The crude product was purified by chromatography (silica, 50:50 ethyl acetate/hexanes) to yield l-methyl-5-nitro-7-azaindole (0.152 g, 72%) as a yellow solid: 1H NMR (500 MHz, CDCl3) delta 9.23 (d, J= 2.4 Hz, IH), 8.76 (d, J= 2.4 Hz, IH), 7.36 (d, J= 3.6 Hz, IH), 6.66 (d, J= 3.5 Hz, IH), 3.96 (s, 3H).
