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. 14432-12-3, name is 4-Amino-2-chloropyridine. A new synthetic method of this compound is introduced below., Computed Properties of C5H5ClN2
A mixture of 2-chloro-4-aminopyridine 3 (127 mg, 1.0 mmol) and KOH (280.6mg, 5.0 mmol) in toluene (4.0 mL) was heated at 170C in a sealed tube for 72h. Themixture was cooled to r.t. and the toluene was removed. The residue was purified byflash chromatography on silica gel (DCM/MeOH/NH4OH: 78/20/2) to give 5 (107 mg,97%) as a pale yellow solid
