152265-57-1, 7-Bromophthalazin-1(2H)-one is a phthalazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
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.
As the paragraph descriping shows that 152265-57-1 is playing an increasingly important role.
