Procedure

The crude 2-benzylamino-2-methyl-4-((tetrahydro-2H-pyran-2-yl)oxy)butanol (10D, 80.1 g, 0.273 mol) was dissolved in 3N HCl (128 mL). After 5 min the mixture was washed with Et2O (200 mL). The aqueous solution was concentrated by rotary evaporation to give a thick oil which was cooled and basified with excess 50% NaOH. The oily amine which formed was extracted with Et2O (3×200 mL). The Et2O extends were combined and concentrated to give 63.6 g of a thick oil. Distillation gave 49.8 g (94%) of 2-benzylamino-2-methyl-1,4-butanediol as a pale yellow oil (bp 168°-170°/0.35 mm) (C,H,N)
