실험 절차

Into an appropriate sized reaction vessel, a mixture of (R)-4-((R)-1-((1-cyclopropyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-benzo[d]imidazol-7-yl)oxy)ethyl)pyrrolidin-2-one: (100.0 mg, 0.24 mmol), 4-bromopyrimidine (77.3 mg, 0.49 mmol), sodium carbonate (77.3 mg, 0.73 mmol) and Pd(PPh3)4 (14.04 mg, 0.01 mmol) was added Dioxane (8 ml), water (1 ml). The reaction mixture was stirred and heated at 120° C. for 3 h. Then, it was filtered through a pad of Celite and partitioned between EtOAc (2×30 mL) and brine (2×10 mL). The combined organic layers were washed with water (2×5 mL), concentrated, and purified by flash chromatography (100% EtOAc to 20% MeOH in EtOAc) to give 45.0 mg (50.9%) of (R)-4-((R)-1-((1-cyclopropyl-5-(pyrimidin-4-yl)-1H-benzo[d]imidazol-7-yl)oxy)ethyl)pyrrolidin-2-one:. 1H NMR (300 MHz, DMSO-d6) δ 9.211 (d, J=1.2 Hz, 1H), 8.80 (d, J=5.1 Hz, 1H), 8.19 (dd, J=2.4, 0.9 Hz, 2H), 8.11 (s, 1H), 7.719 (s, 1H). 7.603 (s, 1H), 4.91-4.83 (m, 1H), 3.77-3.70 (m, 1H), 3.41 (t, J=9.2 Hz, 1H), 3.21 (dd, J=6.6, 6.9 Hz, 1H), 2.87-2.82 (m, 1H), 2.41-2.24 (m, 2H), 1.34 (d, J=6 Hz, 3H), 1.20-1.01 (m, 4H). LCMS-ESI+ (m/z): [M+H]+ calcd for C20H21N5O2: 363.17; found 364.04.
