Application

Methylamine hydrochloride can be used as a reactant to synthesize:
  • Betahistine via aza-Michael reaction with 2-vinylpyridine in water.
  • Azatripyrrolic and azatetrapyrrolic macrocycles by reacting with pyrrole and formaldehyde via base-catalyzed Mannich reaction.
  • Tetrahydropyridines via Aza-Diels–Alder reaction with dienes and aldehydes.
  • N-methylsecondary arylamines from aryl chlorides via nickel-catalyzed amination reaction.
