| | 5,5'-Dimethyl-2,2'-dipyridyl Usage And Synthesis |
| Uses | 5,5'-Dimethyl-2,2'-bipyridine is widely used as an intermediate in organic synthesis and pharmaceuticals. It is also used as a raw material in the synthesis of dyestuffs and agrochemicals. It is used as a precursor for the preparation of 5-methyl-5'vinyl-2,2'-bipyridine. | | Definition | ChEBI: Abametapir is a member of bipyridines. | | Mechanism of action |
5 5'-Dimethyl-2,2-bipyridine works by inhibiting metalloproteinase enzymes that are essential for lice egg growth and development.
| | Synthesis |
2-Amino-5-methylpyridine ((Abametapir))(100) was converted to 2-bromo-5-methylpyridine (101) via the Sandmeyer reaction using bromine and sodium nitrite in 75% yield. Next, 101 was converted to abametapir (XIV) via a palladium-catalyzed homocoupling reaction in 79% yield. Abametapir was finally isolated by crystallization from a water/isopropanol mixture.
