Reaction Steps

The title compound was made in a similar way as that of the compound of example 21, from tert-butyl 9-trityl-9H-purin-6-ylcarbamate (214 mg, 0.449 mmol) and 3-(1-bromoethyl)-4-(3,6-dihydro-2H-pyran-4-yl)-1H-isochromen-1-one (intermediate C19, 94 mg, 0.280 mmol) and 50% dispersion in mineral oil NaH (18 mg, 0.34 mmol) in DMF. This was purified via reverse phase chromatography with a Biotage C18 SNAP column (Phase A, water 95%, ACN 5%, formic acid 0.1%); Phase B ACN 95%, water 5%, formic acid 0.1%). Fractions containing the required product were collected, 1 M HClaqueous (5 ml) was added and concentrated under reduced pressure to give the title compound (6.3 mg, 5.8%) as colourless solid.
