4-Amino-1-benzylpiperidine was used in the preparation of:butyl 4-amino-1-piperidineacetate, key intermediate required for the synthesis of butyl 4-[(4-amino-5-chloro-2-methoxybenzoyl)amino]-1-piperidineacetate5-alkylimino-1,2,4-thiadiazolidine-3-ones, such as 4-ethyl-5-[imino-[1-(phenylmethyl)-4-piperidinyl]]-2-methyl-1,2,4-thiadiazolidin-3-one and 4-benzyl-5-[imino-[1-(phenylmethyl)-4-piperidinyl]]-2-isopropyl-1,2,4-thiadiazolidin-3-oneglycyrrhetinic acid derivatives
