Diethyl Ether → HCID 15895369, compound

Participants

Reaction Steps

N-(2-ethoxymethoxy-4,5-ethylenedioxybenzyl)phthalimide (625 mg, 1.69 mmol) was mixed with 0.2 mL (6.4 mmol) hydrazine in 30 mL ethanol and refluxed for three hr. The reaction mixture was cooled, 30 mL ethyl ether was added to the mixture, and a white precipitate was removed by filtration. The filter cake was washed three times with diethyl ether and the combined organic solutions were evaporated to yield a residue that was partitioned between ethyl ether and 10% sodium hydroxide. The organic phase was washed three times with 10% sodium hydroxide, and the aqueous washes were combined and back-extracted twice with dichloromethane. The organic solutions were combined and washed with brine and dried over sodium sulfate/potassium carbonate. Subsequent evaporation of solvent gave 2-ethoxymethoxy-4,5-ethylenedioxybenzylamine as a light yellow oil (346 g, 86% crude), which solidified upon standing. IR: 3375 cm-1.
