m-Calix[3]amide having pyridine on the benzene ring (PyC3A) was synthesized by the cyclization of methyl 3-nonylamino-5-(pyridin-4-yl)benzoate using lithium 1,1,1,3,3,3-hexamethyldisilazide (LiHMDS). The molecular cage 3Pd center dot 2PyC3A was prepared from a 2:3 mixture of PyC3A and [Pd(dppp)(OTf)(2)] in CDCl3/CD3OD (5/1 in volume). On the other hand, in CDCl3, the formation of a polymeric mixture was confirmed.
