Reaction Steps
4.9 g of 4-(5-undecyl-pyrimidin-2-yl)phenol, 1.4 g of 5-ethyl-2-furancarboxylic acid (prepared as described by Perry et al., Appl. Organomet. Chem. 10, 389–392 (1996) from furan-2-carboxylic acid; m.p. 90° C.) and 2.1 g of dicyclohexylcarbodiimide are stirred for 24 h in 50 ml of dichloromethane at room temperature. Filtration, removal of the dichloromethane by distillation, purification by chromatography (silica gel; dichloromethane/heptane) and recrystallization from acetonitrile affords the target compound as colorless crystals having the phase sequence X 80 (N62) I.
