Reaction Steps

A flask was charged with 14.6 g of magnesium and 270 ml of tetrahydrofuran, to which 64.8 g of 1,4-dibromobutane was added dropwise at 50° C. After the completion of dropwise addition, the solution was stirred at 60° C. for one hour. To the solution below 40° C., 39.0 g of methyl 7-oxa-2-norbornanecarboxylate was added dropwise. The solution was stirred at room temperature for one hour, after which an aqueous solution of ammonium chloride was added for hydrolysis. Ordinary post-treatment yielded 43.7 g of 1-(7-oxanorbornan-2-yl)cyclopentanol.
