Some common heterocyclic compound, 37073-15-7, name is 1-(Methylsulfonyl)-1H-benzo[d][1,2,3]triazole, molecular formula is C7H7N3O2S, 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. Computed Properties of C7H7N3O2S
Example 1 (E)-1-(benzotriazol-1-yl)-3-phenyl-2-propen-1-one 1.42 g (0.01 mol) of trans-cinnamic acid (compound of formula IV) and 1.97 g (0.01 mol) of 1-(methylsulfonyl)benzotriazole are stirred at room temperature in 50 ml of tetrahydrofuran, followed by dropwise addition of 0.014 mol of triethylamine. The solution is then refluxed for 24 hours, and then evaporated under reduced pressure. The residue is taken up in 60 ml of water and extracted with 70 ml of ethyl acetate. The organic phase is dried, filtered and then concentrated under vacuum. The powder obtained is taken up in 50 ml of acetonitrile and filtered off by suction. 2.24 g of a white powder are obtained. Melting point: 157 C.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 37073-15-7, its application will become more common.
