1-Methylethylidene-2-tert-butoxycarbonylhydrazine, glacial acetic acid (150 mL) and 10% palladium on carbon (2.0 g) were placed in a 500 mL Parr flask. The bottle was placed on a Parr apparatus, and after evacuating and flushing the bottle with nitrogen three times, the flask was charged with hydrogen to 40 psi. After hydrogen uptake ceased, the flask was evacuated and flushed with nitrogen. Filtration through celite, eluting with ethyl acetate, and concentration afforded the crude 1-(isopropyl)-2-tert-butoxycarbonylhydrazine as an acetic acid salt.
