Reaction Steps

To a stirred solution of 50 g of 3,3-dimethyl-6-(2-hydroxyethyl)-bicyclo(2.2.2)-octan-2-one (produced according to Example II) in 200 ml of dry pyridine is added 30 g of thionyl chloride. The mixture is stirred at 50° C. for 2 hours and then poured into 50 g of water. The resulting aqueous solution is extracted with three 200 ml portions of ether. The combined ether layers are washed with two 100 ml portions of 5% aqueous HCl and dried over anhydrous sodium sulfate. The ether is stripped and the residue is vacuum distilled, yielding about 42 g of 3,3-dimethyl-6-(2-chloroethyl)-bicyclo(2.2.2)-octan-2-one, having the structure: ##STR33##
