Reaction Steps

1-(4-ethoxycarbonylphenoxy)-14-(4-chlorophenoxy)-tetradec 9-yne (2.00 g.; 0.0041 M.) in acetic acid (15 ml.) was reduced in the presence of hydrogen and PtO2 (0.05 g.) at 60° C. and atmospheric pressure. When hydrogen absorption was complete the solution was filtered, the catalyst washed well with ethanol and the solvents evaporated under reduced pressure to yield a colourless oil. 1-(4-ethoxycarbonylphenoxy)-14-(4-chlorophenoxy)-tetradecane (1.62 g.; 80%) M.P. 72.5°-73.5° C. was obtained as a pure crystalline compound by chromatography of this oil on silica-gel (100 g.).
