Reaction Steps

In a 30 ml-round-bottomed flask, 1.00 g (2.08 mM) of 2-(4-decyloxybenzoylamino)-4-octylphenol, 0.07 g (0.68 mM) of p-toluenesulfonic acid monohydrate and 10 ml of o-dichlorobenzene were placed, followed by stirring for 37 min. at 188°-193° C. After the reaction, o-dichlorobenzene was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (eluent: toluene) to obtain 0.59 g of 2-(4-decyloxyphenyl)-5-octylbenzoxazole (yield: 61.3%). ##STR75##
