실험 절차

8-Chlorotheophylline (10 g, 46.6 mmol) was dissolved in 250 ml of DMF and 8 ml of DIEA, and 2-bromobenzyl bromide (12.2 g, 48.9 mmol) was added. The mixture was stirred at 65° C. for 2 hours. The reaction mixture was added 20 ml of EtOAc and 250 ml of cold water. The white precipitate was collected by filtration to afford compound (10A) as white crystals.
