YieldReaction ConditionsOperation in experiment
68.2% With tetrakis(triphenylphosphine) palladium(0); sodium carbonate; In 1,4-dioxane; water; at 90℃;Inert atmosphere; Example 8C Synthesis of (S)-6-(2-(2-(trifluoromethyl)pyrrolidin-1-yl)pyrimidin-5-yl)pyrazin-2-amine A round bottom flask was charged with 6-chloropyrazin-2-amine (0.401 g, 3.09 mmol), (S)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-(2-(trifluoromethyl)pyrrolidin-1-yl)pyrimidine (1.062 g, 3.09 mmol), Pd(PPh3)4 (0.358 g, 0.309 mmol) and 1,4-Dioxane (Volume: 7.74 ml). The reaction mixture was purged with nitrogen for several minutes before an aqueous 2M sodium carbonate (3.09 ml, 6.19 mmol) was added. The reaction mixture was purged for another 10 minutes under nitrogen before it was placed in a 90° C. oil bath and allowed to stir overnight. 1,4-Dioxane was removed in vacuo and the crude mixture was diluted with EtOAc. The product was wash with water (3*) and brine. The combined organic layers were dried over MgSO4, filtered and concentrated under reduced pressure. The crude material was purified on silica gel using normal phase flash chromatography, eluting with CH2Cl2:MeOH to yield 0.655 g (2.11 mmol, 68.2percent) of the title product; 1H NMR (300 MHz, DMSO-d6) delta 9.01 (s, 2H), 8.26 (s, 1H), 7.83 (s, 1H), 6.55 (s, 2H), 5.16-5.02 (m, 1H), 3.77-3.60 (m, 2H), 2.29-2.01 (m, 4H); m/z [M+H]+=311.12
