Versuchsvorschrift

t-Butylhydrazine (0.1 mol) in 75 ml ethanol was treated with 50% aqueous sodium hydroxide (0.11 mol). Phthalide (0.1 mol) was added and the mixture was refluxed for 5 days. After cooling, water was added and the crude product was isolated by filtration. Filtration through silica gel afforded N'-t-butyl-N-(2-hydroxymethylbenzoyl)hydrazine (3.0 g): m.p. 116°-118° C.
