Procedure
Trimethylsilyl chloride (1.9 ml, 15 mmol) was added dropwise to a stirred solution of 4-bromobenzyl alcohol (2.0 g, 11 mmol) in toluene (25 ml) and pyridine (2 ml) at 0° C. The stirred mixture was heated to ambient temperature during 3 hours. The reaction mixture was filtered and the organic solution evaporated to yield pure 4-bromobenzyl trimethylsilyl ether. The silyl ether can be further purified by distillation (b.p. 73° C., 0.1 mm Hg). Yield after distillation: 1.49 g (50%)
