Hydrazine hydrate (1:1) → 6-(2-Methyl-1,3-dioxolan-2-yl)hexan-1-amine

Participants

Reaction Steps

A mixture of 125.25 g (0.395 mole) of N-[6-(2-methyl-1,3-dioxolan-2-yl)hexyl]phthalimide, 23 ml of 85% hydrazine hydrate, and 370 ml of 95% ethanol was refluxed for four hours, cooled, filtered and stripped. The residue was mixed with 500 ml of water, basified with 2 N NaOH solution and extracted with methylene chloride. The organic layer was separated, dried over anhydrous potassium carbonate, filtered, and stripped to an orange oil. This material was distilled to give 35.70 g (64%) of clear oil bp 80°-83° (0.100 mm).
