実験手順

Tetra-n-butylammonium flouride (1M in THF, 1.27 mL, 1.27 mmol) was added to 1-[2-{[tert-butyl(dimethyl)silyl]oxy}-2-(4-methoxyphenyl)ethyl]-2-thioxo-1,2,3,5-tetrahydro-pyrrolo[3,2-d]pyrimidin-4-one (0.065 g, 0.152 mmol) in THF (8 mL). The mixture was stirred at 50° C. overnight. Ethyl acetate was added, and the organic phase was washed with water and brine, dried (MgSO4), filtered and concentrated. This crude material was purified by preparative HPLC to yield the title compound (0.018 g, 37%) as a solid.
