Chemical Properties

Crystals

Uses

4-Amino-3-methylpyridine is a non depolarizing muscular relaxant with antagonist effect that functions on neuromuscular transmission and in central nervous systems in rats. A central cholinergic agent.

Safety Profile

Moderately toxic by ingestion.When heated to decomposition it emits toxic fumes ofNOx.

Synthesis

1074-98-2

1990-90-5

Step 2: A mixed solution of 3-methyl-4-nitropyridine-N-oxide (30.0 g, 195 mmol) with 10% palladium-carbon catalyst (6.0 g) in ethanol (450 mL) was subjected to a hydrogen atmosphere (5 bar) and the reaction was stirred at room temperature for 36 hours. Upon completion of the reaction, the reaction mixture was filtered through a diatomaceous earth pad to remove the catalyst, followed by evaporation of the solvent under reduced pressure to afford the target product 3-methyl-4-aminopyridine (20.0 g, 95% yield).
