Reaction Steps

4.95 g of 5-bromo-1,2-bis(bromomethyl)-3-methoxybenzene (3-19) was dissolved in 150 ml of anhydrous DMF, to which 5.50 g of potassium carbonate and 4.30 g of tritylamine, and under an argon atmosphere, the resulting mixture was stirred at 90° C. for 8 hours. The reaction solution was poured into water, and extract with chloroform and the resulting organic layer was washed with saturated salt water, and thereafter, the resulting organic layer was dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure, and thereafter, the resulting residue was recrystallized with 2-propanol to obtain 3.35 g of 6-bromo-4-methoxy-2-tritylisoindoline (3-20).
