Reaction Steps

A flask was charged with 9.82 g of magnesium and 150 ml of THF, to which a solution of 43.5 g of 1,4-dibromobutane diluted with 50 ml of THF was added dropwise at 50° C. The solution was stirred for one hour at 65° C., after which 23.5 g of ethyl 3-trimethylsilylpropionate was added dropwise below 50° C. The solution was stirred for one hour at room temperature, after which an aqueous solution of ammonium chloride was added for hydrolysis. This was followed by ordinary post-treatments. Upon vacuum distillation, there was obtained 23.6 g (yield 94%) of 1-(2-trimethylsilylethyl)cyclopentanol.
