9-Benzyloxy-2-cyclopropylmethyl-6-(1-pyrrolo[2,3-b]pyridin-1-yl-cyclopentylmethyl)-3,4-dihydro-2H-pyrazino[1,2-c]pyrimidine-1,8-dione (415) was prepared following the same method as described for 9-benzyloxy-2-methyl-6-(1-pyrrolo[2,3-b]pyridin-1-yl-cyclopentylmethyl)-3,4-dihydro-2H-pyrazino[1,2-c]pyrimidine-1,8-dione (407) from 5-benzyloxy-6-hydroxy-2-(1-pyrrolo[2,3-b]pyridin-1-yl-cyclopentylmethyl)-pyrimidine-4-carboxylic acid cyclopropylmethyl-(2-hydroxyethyl)-amide (414) (130 mg, 0.24 mmol) and was obtained as white solid (56 mg, 46%).
