YieldReaction ConditionsOperation in experiment
With sodium acetate; In ethanol; at 80℃; for 18.0h; tert-Butylhydrazinehydrochloride (5.99 g, 48.1 mmol) was added to EtOH (60 mL) to form a slurry. To this was added NaOAc (7.93 g, 96.7 mmol) and 2-chloroacrylonitrile (5 mL,62.6 mmol). The solution was heated to 80 C for 18 h, cooled, and the solvent removed in vacuo. The residue was slowly diluted with distilled H2O (35 mL) and partitioned between sat. aq NaHCO3 (40 mL) and EtOAc (40 mL). The organic layer was separated and the aqueous layer was extracted with EtOAc (2 × 20 mL). The organic layers were combined, washed with brine (20 mL), dried (MgSO4), and the solvent removed in vacuo to afford a red oil; yield: 7.95 g (91%); bp 93-94C/0.9 Torr (yellow liquid). The product was a 5:1 mixture of the title compound 6c and its 1-tert-butyl-3-amino isomer. The crude product was used to prepare the Meldrum?s acid derivative 3c, which was purified by recrystallization (see below).
