実験手順
A solution of 94.15 parts by weight of 4-(trimethylsilyl)-3-butyn-2-ol (II) in 940 parts by volume of benzene and 4.7 parts by volume of quinoline is hydrogenated at a constant pressure of 2 p.s.i. in the presence of 9.4 parts by weight of 5% palladium on barium sulfate until one equivalent of hydrogen is consumed. The catalyst is removed and the solution is washed twice with 100 parts per volume of 5% aqueous hydrochloric acid and then with water. After drying over sodium sulfate, the solvent is removed and the residue is distilled at 33°-39° C./0.3 mm to give cis-4-(trimethylsilyl)-3-buten-2-ol (III) which has the following structural formula: ##STR9##
