1-Methylpiperidin-4-amine Chemical Properties,Usage,Production

Uses

4-Amino-1-methylpiperidine is used as an organic reagent and pharmaceutical intermediate.

Chemical Properties

Clear colorless to yellow liquid

Synthesis

359878-09-4

41838-46-4

N-((4-methoxyphenyl)methyl)-4-amino-1-methylpiperidine (1 g, 4.27 mmol) was used as starting material, which was dissolved in a methanol solution of 4% formic acid (60 mL). Under argon protection, 10% Pd/C (1 g) was added to the reaction system and the reaction mixture was subsequently heated to reflux for 24 hours. Upon completion of the reaction, the mixture was filtered through diatomaceous earth and the filtrate was acidified with concentrated hydrochloric acid to a pH of about 1. The resulting solution was concentrated to give a yellow oily substance. The oily substance was purified by fast chromatography (eluent: methanol/dichloromethane = 3:7 with 3.5% ammonia) to give 249 mg (51% yield) of 4-amino-1-methylpiperidine (57-MBT36B) as a white solid. Thin layer chromatography (TLC) Rf value was 0.13 (unfolding agent: 10% dichloromethane solution in methanol with 3.5% ammonia). High performance liquid chromatography-mass spectrometry (HPLC-MS, Method B) showed the molecular ion peak MH+ = 115. ultraviolet/mass spectrometry (UV/MS) detection showed a percent purity of -/100.
