Participants

Reaction Steps

A solution containing 9.86 g. of N,N'-(3-heptyne-1,7-diyl)bis(4-trifluoromethoxybenzamide) in 110 ml. of ethanol and 5.0 ml. of pyridine was hydrogenated in a Parr shaker using 1.0 g. of palladium-on-barium sulfate using an initial pressure of hydrogen of 35.5 psi and taking about 40 minutes. The reaction mixture was filtered to remove the catalyst and the filtrate was concentrated in vacuo to remove the sulfate. The white crystalline solid residue was recrystallized from carbon tetrachloride using a small quantity of methanol to yield, as a white microcrystalline powder after drying in vacuo at 60° C. for about 50 hours, 7.6 g. of N,N'-(cis-3-heptene-1,7-diyl)bis(4-trifluoromethoxybenzamide), m.p. 111°-113° C.
