To a solution of 5-methyl-4-oxo-3,4,5,7-tetrahydro-pyrrolo[3,4-d]pyrimidine-6-carboxylic acid tert-butyl ester (1 g, 3.98 mmol) in acetonitrile (40 ml), PyBOP (2.69 g, 5.17 mmol) is added, followed by DBU (1.200 ml, 7.96 mmol). After 20 min, 5-hydroxyindole (1.060 g, 7.96 mmol) is added. The reaction is left stirring at rt overnight. The reaction mixture is then evaporated, the crude product is added to a silica gel column and is eluted with heptane/ethyl acetate (100:0 to 60:40) to give the title compound. MS (ESI) m/z 367.05 (M+1).
