To a solution of 0.080 g (0.31 mmol) of (+/−)-9-Amino-2-pyrimidin-4-yl-5,6,8,9-tetrahydro-7-oxa-1,4-a-diaza-benzocyclohepten-4-one dissolved in 2.60 mL of dimethylformamide was added 0.086 g (0.31 mmol) of 3,4-dihydro-1H-isoquinoline-2,7-dicarboxylic acid 2-tert-butyl ester. To the resulting mixture was added 60 μL (0.37 mmol) of diethyl cyanophosphonate and 40 μL (0.31 mmol) of triethylamine at 0° C. The resulting mixture was stirred at room temperature for 15 hours. Water and ethyl acetate were added and the mixture was stirred. The resulting residue was filtered, washed with water, ethyl acetate and diethyl ether to afford 0.062 g (38%) of the pure product as a white powder.
