Vorschrift

t-Butyloxycarbonylhydrazine (1.26 g) was added portionwise to a solution of 4-bromobenzoyl chloride (2.0 g), and DIPEA (2.37 ml) in DCM (20 ml) and the reaction stirred at room temperature for 18 hours. Ammonium chloride solution was added, the organic phase was separated, dried and the solvent evaporated under vacuum to give 4-bromo-benzoic acid N′-(2,2-dimethyl-propionyl)-hydrazide.
