Procedure

1.00 g (3.64 mM) of 2-octylindan-5-carboxylic acid and 1.13 g (3.62 mM) of 5-decyl-2-(4-hydroxyphenyl)pyrimidine were dissolved in 30 ml of dichloromethane. To the solution, 0.74 g (3.59 mM) of N,N'-dicyclohexylcarbodiimide (DCC) and 0.05 g of 4-pyrrolidinopyridine were added, followed by stirring for 5 hours. The resultant N,N'-dicyclohexylurea was recovered by filtration, washed with dichloromethane, and added to the filtrate. The resultant dichloromethane solution was subjected to distillation under reduced pressure. The residue was purified by silica gel column chromatography (eluent: toluene) and recrystallized from a mixture solvent (toluene/methanol) to obtain 1.23 g of 4-(5-decylpyrimidine-2-yl)phenyl 2-octylindan-5-carboxylate (Yield: 60.3%). ##STR131##
