Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 20265-35-4, name is 2-Methoxy-3-nitropyridine. This compound has unique chemical properties. The synthetic route is as follows. COA of Formula: C6H6N2O3

Method 4 Synthesis of 7-methoxy-1H-pyrrolo[2,3-c]pyridine (Intermediate 5) A solution of R-4 (500 mg, 3.24 mmol) in anhydrous THF (20 mL) is cooled to -78° C. and vinylmagnesium bromide (9.73 mL of a 1 M solution in THF, 9.73 mmol) added. The reaction is stirred at -20° C. for 6 h then quenched with saturated aqueous NH4Cl solution and extracted with EtOAc. The organic phase is concentrated in vacuo and the crude material purified by flash chromatography (SiO2, 2percent to 10percent MeOH in DCM) to give the title intermediate I-5 (100 mg) m/z 148.9 [M+H].

Reference of 20265-35-4, 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.20265-35-4, name is 2-Methoxy-3-nitropyridine, molecular formula is C6H6N2O3, molecular weight is 154.12, as common compound, the synthetic route is as follows.

EXAMPLE 13 Synthesis of 2-methoxy-3-aminopyridine STR28 To a solution of the compound of Example 12 (17.12 g, 0.11 mol) in ethanol (180 mL) in a Parr bottle, was added 4percent Pd/C (3.43 g). The bottle was sealed, purged with nitrogen and was pressurized (5 psi) with hydrogen. After stirring at room temperature for 2 hr, the reaction vessel was vented, purged with nitrogen and filtered. The clear filtrate was concentrated to give the title compound (15.3 g, 90percent). 1 H NMR (CDCl3): 7.58 (dd, J=5, 2 Hz, 1H); 6.87 (dd, J=8, 2 Hz, 1H); 6.72 (dd, J=8, 5 Hz, 1H); 3.98 (s, 3H).

Statistics shows that 20265-35-4 is playing an increasingly important role. we look forward to future research findings about 2-Methoxy-3-nitropyridine.
