Application： 4-(Methylamino)pyridine can be used: To functionalize hypercrosslinked emulsion-templated porous polymers (polyHIPE) to form a highly efficient heterogeneous nucleophilic catalyst for the acylation of a tertiary alcohol. As a reactant to synthesize 4-(N-allyl-N-methylamino)pyridine, which is employed as an intermediate to prepare DMAP/SBA-15 supported catalyst for the synthesis of propylene carbonate. To prepare 5-azaoxindoles via homolytic aromatic substitution； 4-(Methylamino)pyridine was employed as efficient nucleophilic catalyst during the preparation of ultra-high surface area emulsion templated porous polymers
