実験手順

A mixture consisting of 3.52 g of trans-1,4-bis[(4-formylphenoxy)methyl]cyclohexane, 2.34 g of 4-oxo-2-thioxooxazolidine, 0.31 g of sodium acetate and 50 ml of acetic acid was subjected to overnight reflux. After spontaneous cooling, crystals thus formed were collected by filtration and recrystallized from dimethylformamide to obtain 3.75 g of trans-1,4-bis[[4-[(4-oxo-2-thioxo-5-oxazolidinylidene)methyl]phenoxy]methyl]cyclohexane (19-a).
