Procedure

Six grams of the 1,1-dimethoxy-3-hexyne-2-one (of Example I) is stirred under hydrogen gas at one atmosphere in 40 ml hexane containing 0.6 g Lindlar catalyst (palladium on calcium carbonate poisoned with lead acetate) and 4.0 g quinoline. The reaction is terminated when one percent of the starting material (1,1-dimethoxy-3-hexyne-2-one) remains.
