실험 절차

To a pressure vessel was added [3-(2-Chloro-5-fluoro-pyrimidin-4-ylamino)-6,6-dimethyl-4,6-dihydro-1H-pyrrolo[3,4-c]pyrazol-5-yl]-((S)-2,4,5,5-tetramethyl-piperazin-1-yl)-methanone (0.150 g, 0.330 mmol), 2-allyl-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (1.12 g, 6.66 mmol), cesium carbonate (0.543 g, 1.66 mmol), dichloro[1,1-bis(diphenylphosphino)ferrocene]palladium(II) dichloromethane adduct (0.0408 g, 0.0498 mmol), H2O (0.3 mL), and THF (3 mL). The suspension was purged with argon for 2 min, then stirred at 100° C. for 15 h. The cooled solution was filtered to remove undissolved solids and the volatiles removed in vacuo. The residue was redissolved in MeOH (5 mL) and 10% palladium on carbon (0.0400 g, 0.380 mmol) was added. The suspension was evacuated and backfilled with hydrogen for 3 times and allowed to stir for 15 h under hydrogen. The suspension was filtered through Celite, the filter cake washed with CH2Cl2, and the filtrate concentrated. Preparative HPLC provided the desired product I1 as a white solid (0.025 g, 14%).
