الإجراء التجريبي

By the method of Example 2, 4-fluorophenylacetic acid is reacted with 5,6-diamino-1-[2-(4-nitrophenyl)ethyl]-3-propyluracil (6) to yield 8-(4-fluorobenzyl)-3-[2-(4-nitrophenyl)ethyl]-1-propylxanthine. By methods well known in the art, 8-(4-fluorobenzyl)-3-[2-(4-nitrophenyl)ethyl]-1-propylxanthine is reduced with hydrazine hydrate or hydrogen gas in the presence of a palladium catalyst to yield 3-[2-(4-aminophenyl)ethyl]-8-(4-fluorobenzyl)-1-propylxanthine.
