YieldReaction ConditionsOperation in experiment
76% With methanol; 1,8-diazabicyclo[5.4.0]undec-7-ene; triethylamine at 20 - 30℃; for 4h; 1.2 Step 2 (0273) (2R,3R,4S,5R)-2-(6-chloro-4-(2-azaspiro[3.5]nonan-2-yl)-lH-pyrazolo[3,4-d]pyrimidin-l- yl)-5 -(hydro xymethyl)tetrahydrofuran-3,4-diol Id To a solution of (2R,3R,4R,5R)-2-(acetoxymethyl)-5-(4,6-dichloro-lH- pyrazolo[3,4d]pyrimidin-l-yl)tetrahydrofuran-3,4-diyl diacetate lc (3 g, 6.72 mmol) in MeOH (l5mL) was added 2-azaspiro[3.5]nonane (0.84 g, 6.72 mmol) and Et3N (0.94 mL, 6.72 mmol) in sequence at room temperature. After 2h stirring at room temperature, to the mixture was added DBU (1.51 mL, 10.08 mmol). The reaction mixture was further stirred for 2 hrs at room temperature, concentrated in vacuo. The resulting residue was purified by column chromatography on silica- gel with 5% MeOH in DCM as eluent on the TELEDYNE ISCO system to yield Id as white solids (2.lg, yield: 76%), MS (ESI): m/z = 410 [M + 1].
