N,N,N'-trimethyl-propane-1,3-diamine. Stirring was continued 8 hours at room temperature and the mixture was then heated to 80° C. for 16 hours before stripping the solvent in vacuo. The residue was dissolved in 75 ml. ether and added to a slurry of 2.1 g. LiAlH4 in 100 ml. of ether. This mixture was refluxed 2 hours. After cooling, ethyl acetate and then aqueous HCl were added and the mixture was stirred one hour. The clear, two-phase system was separated. The organic layer was dried over MgSO4, filtered, stripped of solvent, and the residue was distilled at 70°-75° C./0.4 mm, producing pure N,N,N'-trimethyl-N'-(3-hydroxypropyl)propane-1,3-diamine.
