Related Products of 3032-81-3, These common heterocyclic compound, 3032-81-3, name is 1,3-Dichloro-5-iodobenzene, 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.
Example 26 3-(3,5-Dichloro-phenylamino)-N-phenyl-benzamide A mixture of 3-amino-N-phenyl-benzamide (2.0 g, 9.4 mmol), 3,5-dichloroiodobenzene (2.65 g, 9.7 mmol), N-ethylmorpholine (1.1 g, 9.5 mmol), and copper(II) acetate (0.1 g, 0.6 mmol) in N,N-dimethylformamide (6 mL) was stirred under an inert atmosphere and heated to reflux. After 120 hours, the mixture was allowed to cool and was stirred into water (300 mL) and acidified with concentrated hydrochloric acid. The mixture was extracted with dichloromethane (300 mL) and the extract separated and washed successively with 2N hydrochloric acid, water, 0.5 M aqueous potassium carbonate, water, and saturated aqueous sodium chloride, then dried over MgSO4. The solution was filtered and stripped of solvent under reduced pressure to leave a solid residue which was subjected to chromatography on a column of silica gel in chloroform to afford the product (0.1 g); m.p. 164-165¡ã C. after recrystallization from ethyl alcohol. Calculated for C19H14Cl2N2O: C, 63.88; H, 3.95; N, 7.84. Found: C, 63.64; H, 4.04; N, 7.61.
Statistics shows that 1,3-Dichloro-5-iodobenzene is playing an increasingly important role. we look forward to future research findings about 3032-81-3.
