Reaction Steps

To a solution of 7-(4-chlorobenzyl)-3-methyl-1-(oxiran-2-ylmethyl)-8-(3-(trifluoromethoxy)phenoxy)-1H-purine-2,6(3H,7H)-dione (100 mg, 0.192 mmol, example 13, step 1) in THF (10 mL) was added dimethylamine hydrochloride (160 mg, 1.98 mmol) and lithium perchlorate (20 mg, 0.189 mmol). The mixture was stirred at 25° C. in a sealed tube for 2 h. The mixture was diluted with ethyl acetate and water. The phases were separated and the organic phase was washed with brine, dried over sodium sulfate, filtered and concentrated to give crude product. This crude material was purified via preparative HPLC to give 7-(4-chlorobenzyl)-1-(3-(dimethylamino)-2-hydroxypropyl)-3-methyl-8-(3-(trifluoromethoxy)phenoxy)-1H-purine-2,6(3H,7H)-dione (50 mg, 46.2% yield) as white solid.
