Versuchsvorschrift

To a solution of 1-(4-methoxybenzyl)-3-methyl-8-(3-(trifluoromethoxy)benzyl)-1H-purine-2,6(3H,7H)— dione (110 mg, 0.238 mmol, intermediate 48) in DMF (4 mL) was added 2-(chloromethyl)-5-methylpyridine (33.8 mg, 0.238 mmol, intermediate 50), followed by potassium carbonate (49.5 mg, 0.358 mmol). The reaction was stirred at 55° C. for 2 h. The mixture was partitioned between ethyl acetate and water. The organic phase was washed with brine, dried over sodium sulfate, filtered and concentrated to give a white solid product (120 mg, 88.8% yield) which was used without purification. LCMS MH+ 566.
