Reaktionsschritte

This compound was prepared by a method similar to that described in example 79 except that pyrimidine-5-carboxylic acid was used in place of N-acetyl-6-amino-2-pyridine carboxylic acid, the reaction was performed using 0.75 equivalents of 3-cyclopropylmethyl-8-[4-(methylamino)-benzyl]-1-(2-fluorobenzyl)-3,7-dihydropurine-2,6-dione and 1.5 equivalent of 4-dimethylaminopyridine was added as the final reagent to the reaction mixture. Purification was performed by chromatography using silica eluted with 94:6 ethyl acetate/methanol followed by trituration with hot acetonitrile to give the product as a colorless solid (72%). MS, m/z(M+H)=540.2161.
