Direct halogenation of pyridine with chlorine gas above 270 °C gives a mixture of 2-chloropyridine and 2,6-dichloropyridine. [1] 2- and 4-chloropyridine are prepared from the corresponding pyridinols using phosphoryl chloride. [1]
[3] [4] [5] The pyramid was divided into basic foods at the base, including milk, cheese, margarine, bread, cereals and potato; a large section of supplemental vegetables and fruit; and an apex of supplemental meat, fish and egg. The pyramid competed with the National Board's "dietary circle", which KF saw as problematic for resembling a cake ...

2-Chloropyridine is an aryl chloride with the formula C 5 H 4 ClN. It is a colorless liquid that is mainly used to generate fungicides and insecticides in industry. It also serves to generate antihistamines and antiarrythymics for pharmaceutical purposes. [2] It is one of three isomers of chloropyridine.
Experts agree that a diet rich in fruits and veggies is the way to go. Fruits can provide essential nutrients, fiber and a host of other health benefits. If you enjoy fruits frequently, that's great.
The reaction of 3-bromo-4-chloropyridine with furan and lithium amalgam gives 1,4-epoxy-dihydroquinoline through the 2,3-pyridyne intermediate. The reaction of 4-bromopyridine with sodium in liquid ammonia gives both 3-aminopyridine and 4-aminopyridine through the 3,4-pyridyne intermediate and an E1cB-elimination reaction .
