7-Benzyl-8-chloro-1,3-dimethyl-3,7-dihydropurine-2,6-dione (2A) (100 mg, 0.33 mmol), (3S)-(−)-3-(tert-butoxycarbonylamino)pyrrolidine (305 mg, 1.64 mmol), and triethylamine (0.46 ml, 3.28 mmol) was dissolved in 20 ml of 2-propanol and 5 ml of DMF and the mixture was subjected to microwaves (method F, 130° C., 300 W) for three hours. The solvent was evaporated and the crude product was purified by preparative HPLC (method A1, Rt=11.75 min.). Evaporation of the solvent afforded compound (3A) as a brown oil.
