2-Aminopropanol → 2,2'-Iminodipropanol

Participants

Reaction Steps

Platinum dioxide (40 mg) was added to a solution of dl-2-amino-1-propanol (6.4 ml) and hydroxyacetone (7.0 g) in methanol (75 ml) over 3 A molecular sieves. The reaction mixture was hydrogenated at 60 psi. for 18 hours, after which time the catalyst was filtered off and the solvent removed under reduced pressure. The crude product was purified by distillation, b.pt. 94° [email protected] mbar to afford 2-[(2-hydroxy-1-methylethyl)amino]-1-propanol (3.66 g) as a yellow oil.
