Procedure

A solution was prepared of 2,4-dimethyl-4-isopropyl-5-(bromomethylene)-2-oxazolinium bromide in ethanol and allowed to stand at room temperature. The solvent gradually evaporated and the solid residue was recrystallized from ethanol to yield 1-bromo-3,4-dimethyl-3-amino-2-pentanone hydrobromide having a melting point of about 158°-160° C. The material was identified by the n.m.r. spectrum.
