Reaction Steps

To a solution of the 8-bromo-7-(4-chlorobenzyl)-1-(3-hydroxypropyl)-3-methyl-1H-purine-2,6(3H,7H)— dione (50 mg, 0.116 mmol, intermediate 63) in DMF (2 mL) was added 3-chloro-5-(trifluoromethoxy)phenol (29.82 mg, 0.140 mmol) followed by potassium carbonate (24.24 mg, 0.175 mmol). The reaction was stirred at 85° C. for 2 h. The reaction was cooled and partitioned between ethyl acetate and water. The organic phase was washed with brine, dried over sodium sulfate, filtered and concentrated to give crude product, which was purified by preparative HPLC to give 8-(3-chloro-5-(trifluoromethoxy)phenoxy)-7-(4-chlorobenzyl)-1-(3-hydroxypropyl)-3-methyl-1H-purine-2,6(3H,7H)-dione (35 mg, 53.5% yield) as white solid. 1H-NMR (CD3OD) δ 7.458-7.435(m,3H), 7.381-7.365(m,3H), 7.361(s,1H), 5.507(s,2H), 4.138-4.102(t,2H), 3.640-3.608(t,2H), 3.448(s,3H), 1.905-1.871(m,2H). LCMS retention time 3.325 min; LCMS MH+ 559.
