1,3-Propanediamine → HCID 66880063, compound

Participants

Reaction Steps

Sodium acetylphosphinate (2.6 g, 0.02 mol) and 1,3-diaminopropane (1.7 ml, 1.5 g, 0.02 mol) were stirred together in ethanol (60 ml) for 21/2 days, giving a cloudy pale yellow solution. This was evaporated inder reduced pressure, giving a sticky hydroscopic yellow solid, which contains ethanol by nmr. The solid was dissolved in ethanol, toluene added and re-evaporated to dryness, giving a yellow foam, mp 144°-6°, decomp (3.2 g, 86%). NMR was consistent with the desired structure.
