New learning discoveries about 152265-57-1

The chemical industry reduces the impact on the environment during synthesis,152265-57-1,7-Bromophthalazin-1(2H)-one,I believe this compound will play a more active role in future production and life.

152265-57-1, 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. 7-Bromophthalazin-1(2H)-one, cas is 152265-57-1,the phthalazine compound, it is a common compound, a new synthetic route is introduced below.

To a stirred solution of 7-bromophthalazin-l(2H)-one (1,00 g, 4.44 mmol, 1,0 eq) in DMF (10 ml) was added 2-(chloromethyl)- oxirane (1.24 g, 13 3 mmol, 3.0 eq) and CS2CO3 (4.35 g, 13.3 mmol, 3.0 eq), and the resultant mixture was heated to 90 C for 0.5 hour. The reaction mixture was diluted with cold water, and was extracted with EA. Organic phase was washed with water twice followed by brine, dried over MgS04, and was concentrated to dryness. The obtained residue was used directly in next step without further purification.

The chemical industry reduces the impact on the environment during synthesis,152265-57-1,7-Bromophthalazin-1(2H)-one,I believe this compound will play a more active role in future production and life.
