실험 절차
To a solution of 52.0 g (0.25 mole) of this ketone in 400 ml of chloroform is added a solution of 40.0 g (0.25 mole) of bromine in 200 ml of chloroform at such a rate as reaction mixture decolorizes (50 minutes after a 25 minute initiation period). Solvent is evaporated and the residue recrystallized from methanol to give 54.1 g (75%) of methyl 5-(2-bromoacetyl)-2-methoxybenzoate, m.p. 149°-153° C. A second crop of 10.4 g is obtained from the mother liquor.
