A solution of 0.057 M DMD in acetone (47.4 ml, 2.7 mmol) was added to a cold stirred solution of N-tert-butyl-N-benzylamine (Aldrich, 0.4417 g, 2.7 mmol) in acetone (5 ml). The reaction mixture was stirred for fifteen minutes in an ice bath. Solvent was removed on a rotary evaporator to give a white, microcrystalline solid (0.4803 g, 99.6% yield), mp 58-60. Flash chromatography of the solid over silica gel and elution with a 90:10 mixture of petroleum ether (bp 35-60) and ethyl acetate gave the hydroxylamine as a white crystalline solid, mp 60-61.5 (reported mp 71-73, Emmons 1957). Distillation of this material gave a solid with the same mp.
