Participants

Reaction Steps

8-Chloro-7-(2-iodobenzyl)-1,3-dimethyl-3,7-dihydropurine-2,6-dione (5A) (100 mg, 0.23 mmol) and (3S)-(−)-3-(tert-butoxycarbonylamino)pyrrolidine (216 mg, 1.16 mmol), and triethylamine (0.32 ml, 2.32 mmol) were dissolved in 20 ml of 2-propanol and the mixture was subjected to microwaves (method F, 130° C., 300 W) for three hours. The solvents were evaporated and the crude product was purified by preparative HPLC (method A1, Rt=12.99 min.). Evaporation of the solvent afforded compound (7A) as white crystals.
