Procedure

A solution of 9-{(3aR,4R,6S,6aR)-6-[3-(tert-butyl)-1,2,4-oxadiazol-5-yl]-2,2-dimethyltetrahydrofuro[3,4-d][1,3]dioxol-4-yl}-N-(2,4-difluorophenyl)-9H-purin-6-amine (18.3 mg) in a cold mixture of trifluoroacetic acid:water (9:1; 1 ml) was kept at 4° C. for 18 h. The resulting solution was basified in an ice bath with a saturated solution of sodium bicarbonate (20 ml), extracted with ethyl acetate (2×20 ml), the extracts dried (MgSO4) and evaporated to dryness in vacuo to afford the title compound (14.3 mg) as a purple solid.
