Reaction Steps

Step iii) In a 50 ml-round-bottomed flask, 10 g of polyphosphoric acid, 0.40 g (1.32 mM) of 2-amino-4-(trans-4-octylcyclohexyl)phenol and 0.31 g (1.32 mM) of 4-octylbenzoic acid were placed, followed by stirring for 4 hours at about 250 ° C. After the reaction, the reaction mixture was poured into water and an insoluble matter was recovered by filtration. The insoluble matter was added to 10% K2CO3 and sufficiently stirred, followed by recovery of a solid. The solid was washed with water and purified by silica gel column chromatography (eluent: toluene) to obtain 0.11 g of 2-(4-octylphenyl)-5-(trans-4-octylcyclohexyl)benzoxazole (yield: 16.7%). ##STR18##
