Procedure

Bromine (26.42 g, 0.165 mole) was slowly added to a stirred solution of 19.2 g (0.165 mole) of 3-methoxy-3-methyl-2-butanone in 400 ml. diethyl ether at 15° C. After the addition was complete, the solvent was evaporated, and the residual orange oil distilled to give 22 g (68% yield) of 1-bromo-3-methoxy-3-methyl-2-butanone, b.p. 57°-59° C./1.7 mm. Hg.
