Procedure: 3.22 ml of bromoacetyl bromide were added dropwise under an inert gas atmosphere at 0° C. to 19.23 g of tritylamine in 50 ml of chloroform and then the mixture was stirred for one hour while allowing the temperature to rise to ambient temperature. After filtration of the precipitate, the organic phase was washed with 1N sodium hydroxide, dried, evaporated under reduced pressure until a residue was obtained which was purified by crystallization from ether to obtain 8.5 g of the expected amide. to rise to ambient temperature After filtration of the precipitate the organic phase was washed with 1N sodium hydroxide dried evaporated under reduced pressure until a residue was obtained which was purified by crystallization from ether

Procedure: 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). extract with chloroform the resulting organic layer was washed with saturated salt water the resulting organic layer was dried over anhydrous magnesium sulfate The solvent was distilled off under reduced pressure the resulting residue was recrystallized with 2-propanol
