72702-95-5,72702-95-5, 2-(3-(4-Bromo-2-fluorobenzyl)-4-oxo-3,4-dihydrophthalazin-1-yl)acetic acid is a phthalazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
EXAMPLE 54 Acetyl chloride (10 ml.) was added to stirred methanol (150 ml.) to give a solution of hydrogen chloride in methanol and methyl acetate. 2-(2-Fluoro-4-bromobenzyl)-1,2-dihydro-1-oxophthalazin-4-ylacetic acid (2.1 g.) was added to this solution and the mixture was heated under reflux for 18 hours, and then cooled to room temperature. The solid which crystallized out was separated by filtration and recrystallized from methanol to give methyl 2-(2-fluoro-4-bromobenzyl)-1,2-dihydro-1-oxophthalazin-4-ylacetate (1.4 g.), m.p. 151-153 C.
As the paragraph descriping shows that 72702-95-5 is playing an increasingly important role.
