Procedure

8.62 g (33.7 mmol) of 4-(2-benzyloxyethyl) phenyl boronic acid, 9.13 g (33.7 mmol) of 2-chloro-5-decyloxypyrimidine, 1.29 g of tetrakis (triphenylphosphine) palladium, 54 ml of 2M-sodium carbonate solution, 54 ml of toluene and 27 ml of ethanol were heated at 80° C. for 4 hours under presence of nitrogen. After reactions had been completed, extraction with toluene was performed. Then, the extracted solution was dried with anhydrous sodium sulfate. The solvent was removed by filtration, and then refining was performed by recrystallization (toluene/methanol) so that 9.30 g of 2-{4-(5-decyloxypyrimidine-2-yl) phenyl}ethylbenzylether was obtained (yield 62%).
