Reaction Steps

To a solution of 6-((5-chloro-3H-[1,2,3]triazolo[4,5-d]pyrimidin-3-yl)methyl)quinoline (393 mg, 1.33 mmol) in DME (8 mL) was added 1-(2-(tetrahydro-2H-pyran-2-yloxy)ethyl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (642 mg, 1.99 mmol) and Cs2CO3 (1.30 g, 3.98 mmol) in H2O (1.3 mL). The reaction mixture was degassed twice. The palladium catalyst Pd(dppf).CH2Cl2 (63 mg, 0.077 mmol) was added and the reaction mixture was degassed for two more times, and heated to 80° C. for 15 h under nitrogen. After cooling to room temperature, the solvent was removed under reduced pressure. Flash chromatography of the residue over silica gel, using 50% hexane in EtOAc to 100% EtOAc to 10% MeOH in EtOAc, gave the desired product (237 mg, 39%). 1H NMR (300 MHz, CDCl3) δ 1.23-1.82 (m, 6H), 3.42-4.59 (m, 7H), 6.04 (s, 2H), 7.41 (m, 1H), 7.82-7.85 (m, 1H), 7.90 (m, 1H), 8.08-8.15 (m, 2H), 8.31 (s, 1H), 8.34 (s, 1H), 8.90-8.92 (m, 1H), 9.46 (s, 1H); LCMS (APCI) m/z 457.2 (M+H+).
