2-Aminopyridine is an organic compound with the formula H 2 NC 5 H 4 N. It is one of three isomeric aminopyridines. It is a colourless solid that is used in the production of the drugs piroxicam, sulfapyridine, tenoxicam, and tripelennamine. It is produced by the reaction of sodium amide with pyridine, the Chichibabin reaction. [3]
2-Bromopyridine reacts with butyllithium to give 2-lithiopyridine, [2] which is a versatile reagent. [3] Pyrithione can be prepared in a two-step synthesis from 2-bromopyridine by oxidation to the N-oxide with a suitable peracid followed by substitution using either sodium dithionite or sodium sulfide with sodium hydroxide to introduce the thiol functional group.
[4] [5] Bromazolam is a non subtype selective agonist at the benzodiazepine site of GABA A receptors, with a binding affinity of 2.81 nM at the α 1 subtype, 0.69 nM at α 2 and 0.62 nM at α 5. [6] The "common" dosage range for users of bromazolam was reported to be 1–2 mg, suggesting its potency is similar to alprazolam.
3-Bromopyridine is an aryl bromide and isomer of bromopyridine with the formula C 5 H 4 BrN. It is a colorless liquid that is mainly used as a building block in organic synthesis. [1] [2] It participates as a substrate in many reactions associated with aryl halides, e.g., the Heck reaction [3] and Buchwald-Hartwig coupling. [4]
The methylthio and amino pyridines were found to be formed in the same ratio. [4] In 1972 Kramer and Berry inferred the formation of 3,4-pyridyne in gas-phase photolysis of pyridine-3-diazonium-4-carboxylate via time-of-flight mass spectrometry. The dimer compound diazabiphenylene was detected. [5]
Vadadustat, sold under the brand name Vafseo, is a medication used for the treatment of symptomatic anemia associated with chronic kidney disease. [2] [3] Vadadustat is a hypoxia-inducible factor prolyl hydroxylase inhibitor.

This is a list of aminorex analogues. Aminorex itself is a stimulant drug with a 5-phenyl-2-amino-oxazoline structure. It was developed in the 1960s as an anorectic, [1] [2] [3] but withdrawn from sale after it was discovered that extended use produced pulmonary hypertension, often followed by heart failure, which resulted in a number of deaths.
