9-Benzyloxy-2-isopropyl-6-(1-pyrrolo[2,3-b]pyridin-1-yl-cyclopentylmethyl)-3,4-dihydro-2H-pyrazino[1,2-c]pyrimidine-1,8-dione (411) 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 (2-hydroxyethyl)-isopropylamide (410) (110 mg, 0.21 mmol) and was obtained as an off-white solid (40 mg, 38%).
