Name: Piperidin-4-amine dihydrochloride. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Piperidin-4-amine dihydrochloride, is researched, Molecular C5H14Cl2N2, CAS is 35621-01-3, about Efficient and Scalable Method for the Selective Alkylation and Acylation of Secondary Amines in the Presence of Primary Amines. Author is Laduron, Frederic; Tamborowski, Vanessa; Moens, Luc; Horvath, Andras; De Smaele, Dirk; Leurs, Stef.
Selective substitution of secondary amines in the presence of primary amines is performed by using the reaction solvent, Me isobutylketone (MIBK), as a temporary protecting group for the primary amine. After acylation or alkylation of the secondary amine, the resulting imine intermediate is smoothly hydrolyzed, leading to the free primary amine in high yield and purity. This procedure represents a cheap and scalable alternative to multistep methods requiring several protections and deprotections.
