A two-step continuous flow synthesis of 4-nitropyridine.
The results are consistent with a reaction scheme in which the formed N-nitro-1,4-dihydro-4-pyridinesulfonic acid (2) did not react directly to give 3-nitropyridine but existed in equilibrium with.
CN105523995A - Preparation method for malaridine.
The invention provides a green environment-friendly preparation method for a malaridine intermediate 2-methoxy-5-aminopyridine. The preparation method comprises the specific method: with 2-aminopyridine as a raw material, nitrating 2-aminopyridine with a mixed acid in the presence of a solvent to obtain 2-amino-5-nitropyridine; and carrying out hydrolysis, chlorination, methoxylation and.
Novel and Efficient Synthesis of Benzimidazole and.
The total yield is 36-40% (1, 2, 3). A semipreparative scale three-stage synthesis including pyridine-N-oxide and 4-nitropyridine-N-oxide as an intermediates is preferable. At the third stage 4-nitro-pyridine-N-oxide was reduced with iron and acetic acid at reflux temperature to produce 4-aminopyridine in quantitative yield. The reaction.
