Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 78607-36-0, name is 2-Chloro-3-iodopyridine. A new synthetic method of this compound is introduced below., Quality Control of 2-Chloro-3-iodopyridine
Preparation of amine building block A46 tert-Butyl 2- (pyridin-4-ylmethyl) -5, 6-dihydroimidazo [1,2- a]pyrazine-7 (8H) -carboxylateProcedure for step- 1 : To a THF solution (40 ml) of Diisopropyl amine (4.46 ml, 1.5 eqv) was added BuLi ( 1.88 M, 1.5 eqv) at -15C and the resulting reaction mixture was allowed to stir at same temperature for 20 minutes. It was then cooled to -78C and 2-chloro-3-iodopyridine (5g, 20.92 mmol) in THF (10 ml) was added dropwise at the same temperature and allowed to stir for 1 hr at -780C. Reaction was quenched with water ( 10 ml), stirred at ambient temperature for 15 minutes and extracted with ethyl acetate. Organic layer was washed successively with brine and finally dried over sodium sulfate. Evaporation of organic layer under reduced pressure gave the crude product which was immediately used in the next step without any further purification. Yield : 80% (Crude)
