Reaction Steps
To a solution of p-hydroxybenzoic acid benzyl ester (68.4 g, 0.3 mol) in N,N-dimethylformamide (274 g) sodium carbonate (15.9 g, 0.15 mol) was added, and stirred at 100° C. Then, p-xylylenedichloride (26.2 g, 0.15 mol) was added to the reaction mixture in 10 minutes, and stirred at 100° C. for one hour. Water was added to the resultant to separate a clued precipitate. The precipitate was filtered, added to N,N-dimethylformamide to be dissolved at 90° C., cooled, filtered, and dried to give a white crystal of 1,4-bis(p-carbobenzyloxyphenoxymethyl)benzene (27.8 g, yield 33.0): m.p. 154°-157° C.
