Related Products of 1594-58-7 ,Some common heterocyclic compound, 1594-58-7, molecular formula is C6H7N3O, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
5-(Chloromethyl)-3-(pyridine-2-yl)-1 ,2,4-oxadiazole (SO2-065): To a solution of N- hydroxypicolinimidamide (0.2g g, 1 .5 mmol) in DCM (20 ml) and chloroacetyl chloride (0.2 g, 1 .8 mmol) at 0 C, diisopropylethylamine (0.23 g, 1 .8 mmol) was added (dropwise). The mixture was warmed up to r.t. and stirred for 24 h. and organic solvent was evaporated and the residue was refluxed overnight in toluene (20 ml_) to complete the cyclization. The product obtained was purified using Si02 chromatography (EtOAc: hexane gradient elution). The required compound SO2-065 (0.24 g, 81 %) was obtained as a white solid.1 H NM R (400 M Hz, CDCI3) delta 8.81 (ddd, J = 4.8, 1 .6, 1 .0 Hz, 1 H), 8.14 (d, J = 7.9 Hz, 1 H), 7.87 (ddd, J = 7.9 Hz, 4.8 , 1 .8 Hz, 1 H), 7.46 (ddd, J = 7.7, 4.8, 1 .2 Hz, 1 H), 4.79 (s, 2H).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,1594-58-7, its application will become more common.
