実験手順
A solution of 1.54 g. of ethyl 2,2-dimethylspiro[2.4]hepta-4,6-diene-1 carboxylate prepared in Example I, above, in 30 ml. of ethanol was catalytically reduced over 50 mg. of pre-reduced platinum oxide. The theoretical amount of hydrogen was taken up over a 3 hr. period. The catalyst was removed by filtration and the alcohol was removed at reduced pressure. The residue, 1.5 g. (100%) could be used directly without further purification.
