実験手順
4-(4-Pyridyl)-3-butyn-1-ol (3.5 g) was dissolved in methanol (100 mL) in a Parr hydrogenation bottle and platinum (IV) oxide [Adams' Catalyst] (0.3 g) was added. The Parr bottle was placed on a Parr hydrogenation apparatus and the solution hydrogenated at 40 psi for 2.5 h after which time the starting material had been judged to be consumed by TLC. The spent catalyst was removed by filtration through a Celite pad and the pad carefully washed with more methanol. The combined filtrates were evaporated under reduced pressure on a rotary evaporator and the oily residues then subjected to column chromatography on a short silica column using neat ethyl acetate as the eluant to provide the title compound (3.0 g).
