2-Chloro-3-cyanopyridine Chemical Properties,Uses,Production

Chemical Properties

white to light yellow crystal powder

Uses

2-Chloro-3-cyanopyridine (cas# 6602-54-6) is a compound useful in organic synthesis.

Reactions

2-Chloro-3-cyanopyridine is sensitive to oxidizing agents, it can undergo reduction and condensation reactions.

Hazard

2-Chloro-3-cyanopyridine has acute toxicity (Oral) and acute toxicity (Inhalation). It causes skin irritation and serious eye irritation.

Synthesis

2-Chloro-3-cyanopyridine is synthesized from 3-cyanopyridine. First, 3-cyanopyridine is treated with 28-31% H2O2 solution. After standing, the mixture is evaporated to yield nicotinamide-N-oxide. This oxide is then reacted with POCl3 at 35-80C. Additional POCl3 is added, and the mixture stands to form the chlorination solution. This solution undergoes reduced-pressure distillation. It is then cooled, and cold water is added. Filtration yields a solid phase. The solid is dissolved in a methanol-water system. Activated carbon is added for decolorization, followed by filtration. The filtrate is evaporated until crystals precipitate. Cooling gives the recrystallized product, which is finally dried under vacuum.
