実験手順

tert-Butyldimethylsilyl chloride (309 mg, 2.047 mmol) was added to a solution of 7-(1-(4-chlorothiazol-2-yl)-3,4-dihydroxybutyl)-5-(3-fluorophenyl)-1,3-dimethyl-1H-pyrrolo[3,4-d]pyrimidine-2,4(3H,6H)-dione (817 mg, 1.706 mmol), imidazole (232 mg, 3.41 mmol) and DMAP (20.84 mg, 0.171 mmol) in DMF (15 mL). The mixture was stirred at room temperature for 50 mins. A further portion of tert-butyldimethylsilyl chloride (100 mg, 0.662 mmol) was added and the mixture stirred for a further 1 hour. The reaction mixture was diluted with EtOAc and washed with 0.1M HCl(aq) (1×) and brine (3×). The organic phase was dried over sodium sulfate and evaporated under vacuum. Purification by chromatography on silica, eluting with 0-60% EtOAc/hexane, afforded the title compound as a mixture of diastereomers.
