New downstream synthetic route of 1147558-43-7

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4-Amino-3-chloro-5-fluorobenzonitrile, other downstream synthetic routes, hurry up and to see.

Application of 1147558-43-7, The chemical industry reduces the impact on the environment during synthesis 1147558-43-7, name is 4-Amino-3-chloro-5-fluorobenzonitrile, I believe this compound will play a more active role in future production and life.

3.123.2. Step ii): 4-[[6-[bis[(4-methoxyphenyl)methyl]amino]-4-(methylamino)-5-nitro-2- pyridyl]amino]-3-chloro-5-fluoro-benzonitrtte A mixture of 6-chloro-N2,N2-bis[(4-methoxyphenyl)methyl]-N4-methyl-3-nitro-pyridine-2,4- diamine (3.39 mmol), 4-amino-3-chloro-5-fluoro-benzonitrile (6.78 mmol) and CS2CO3 (13.6 mmol) in DMA (15 mL) is stirred for 16 h at 120 C. A solution of saturated NH4C1 is added to the mixture. The solid is filtered out and further washed with water. The solid is taken up in EtOAc and the organic mixture is washed (H20 and brine), dried (Na2S04) and concentrated. The residue is purified by flash column chromatography (S1O2, 100:0 to 50:50 petroleum ether/EtOAc) to afford the desired product.

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4-Amino-3-chloro-5-fluorobenzonitrile, other downstream synthetic routes, hurry up and to see.

Continuously updated synthesis method about 1147558-43-7

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4-Amino-3-chloro-5-fluorobenzonitrile, other downstream synthetic routes, hurry up and to see.

Application of 1147558-43-7, 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. 1147558-43-7, name is 4-Amino-3-chloro-5-fluorobenzonitrile belongs to nitriles-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.

3-Chloro-5-fluoro-4-nitrobenzonitrile Sodium perborate tetrahydrate (131 g, 851 mmol) in acetic acid (200 mL) was heated to 60 C. A solution of 4-amino-3-chloro-5-fluorobenzonitrile (29.02 g, 170 mmol) in acetic acid (500 ml.) was added dropwise and the reaction was stirred at 60 C for 16 h. The LCMS the indicated the reaction showed -50% conversion. Additional sodium perborate tetrahydrate (14.4 g) was added and the reaction stirred at 70 C for 2 h. Then additional sodium perborate tetrahydrate (70 g) was added and the reaction was stirred at 80 C for 5 h, followed by RT for 2 days. The reaction was then poured into ice water and extracted with EtOAc (3x). The combined organic extracts were washed with H20 (2x), brine, dried over MgS04 and concentrated. When most of the acetic acid was evaporated, water was added to the residue. The orange precipitate was collected by filtration, washed with H20 and air dried to give the crude product as an orange solid. NMR showed the product contaminated with -10% of starting material. This product was used without any further purification.

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4-Amino-3-chloro-5-fluorobenzonitrile, other downstream synthetic routes, hurry up and to see.
