3-Piperidinamine, N,4-dimethyl-1-(phenylmethyl)-, hydrochloride (1:2)

It serves as the precursor to the chiral piperidine core, in which the N-benzyl group is removed via hydrogenation to allow N-acylation, providing the 3-aminopiperidine moiety essential for Tofacitinib’s structure. 3-Piperidinamine, N,4-dimethyl-1-(phenylmethyl)-, hydrochloride (1:2) acts as a critical intermediate in the synthesis of Tofacitinib.
