Versuchsvorschrift

To 3-tert-butyl-4-hydroxybenzaldehyde (3 gm) in acetic acid (30 ml) was added dropwise bromine (1.5 ml). The mixture was stirred at 25° for 3 hours and the solvent removed in vacuo. Recrystallisation of the residue from aqueous ethanol gave 3-bromo-5-tert-butyl-4-hydroxybenzaldehyde (3.2 gm) m.p. 126°.
