In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 130838-36-7, name is 2,6-Dichloropyrimidine-4,5-diamine, the common compound, a new synthetic route is introduced below. Recommanded Product: 130838-36-7
4, 5-Diamino-1,6-DICHLOROPYRIMIDINE (0,55MMMOL), prepared as described in Example 16, was suspended in water (2 ml) and heated to dissolve. After cooling the solution in the ice-water bath, acetic acid (2ml) was added to the solution. Sodium nitrite in water (0,5 MOL/1-2 ml) was added to this stirred solution at 0C during 15 minutes. After next 20 minutes in the ice-water bath, the reaction mixture was etracted with diethyl ether. The etheric solution was neutralized and dried and then evaporated to give the crude product (100%). This product was purified by crystallization from absolute diethyl ether. Yield= 47% m. p. 260C. TLC (I, 12: 2: 1). RF= 0,22. MS: 188,0 (100%, M-H+), 190,0 (65 %, M-H+)
The synthetic route of 130838-36-7 has been constantly updated, and we look forward to future research findings.
