Participants

Reaction Steps

To a solution of 8-(4-chloro-3-(trifluoromethyl)phenoxy)-7-(4-chlorobenzyl)-3-methyl-1-(2-(2-(tetrahydro-2H-pyran-2-yloxy)ethoxy)ethyl)-1H-purine-2,6(3H,7H)-dione (100 mg, 0.15 mmol) in ethanol (5 mL) was added acetyl chloride (0.2 mL) at 0° C. The mixture was stirred at room temperature for 1 h. The mixture was partitioned between ethyl acetate and water. The organic phase was dried over sodium sulfate, filtered and concentrated to give a crude product, which was purified via preparative HPLC to give 8-(4-chloro-3-(trifluoromethyl)phenoxy)-7-(4-chlorobenzyl)-1-(2-(2-hydroxyethoxy)ethyl)-3-methyl-1H-purine-2,6(3H,7H)-dione (37 mg, 43.1% yield) as white solid. 1H-NMR (DMSO-d6) δ 7.95(d, 1H), 7.85(d, 1H), 7.77-7.80(m, 1H), 7.44(s, 4H), 5.44(s, 2H), 4.58-4.61(m, 1H), 4.06(t, 2H), 3.59(t, 2H), 3.43-3.46(m, 4H), 3.29(s, 3). LCMS retention time 3.070 min; LCMS MH+ 573.
