実験手順

To a degassed solution of 2-(4-(5-bromo-2-methyl-2,3-dihydrobenzofuran-2-yl)piperidin-1-yl)-5-cyclopropylpyrimidine (424 mg, 1.02 mmol), tert-butyl 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-5,6-dihydropyridine-1(2H)-carboxylate (380 mg, 1.23 mmol), and K2CO3 (424 mg, 3.07 mmol) in dioxane (6 mL) and water (2 mL) was added Pd(Ph3P)4 (59.1 mg, 0.051 mmol). Upon completion of addition, the reaction mixture was heated in 100° C. oil bath for 3 hours. After this time, the reaction mixture was cooled to room temperature, diluted with water, and extracted with CH2Cl2 (3×5 mL). The combined organic layers were dried (Na2SO4), filtered, and concentrated to yield a residue. The residue was purified by column chromatography (silica gel, hexanes/EtOAc gradient 0 to 50% EtOAc) to afford Compound 11F as a white solid (360 mg, 0.697 mmol, 68% yield). 1H NMR (500 MHz, CDCl3) δ ppm 8.11 (s, 2 H), 7.15 (s, 1 H), 7.13 (d, J=8.5 Hz, 1 H), 6.65-6.71 (m, 1 H), 5.88 (br. s., 1 H), 4.75-4.87 (m, 2 H), 4.05 (br. s., 2 H), 3.73 (t, J=6.2 Hz, 1 H), 3.62 (t, J=5.5 Hz, 2 H), 3.16 (d, J=15.7 Hz, 1 H), 2.74-2.87 (m, 2 H), 2.39-2.54 (m, 2 H), 1.86-1.96 (m, 2 H), 1.76-1.84 (m, 1 H), 1.67-1.74 (m, 1 H), 1.61 (m, 1 H), 1.49 (s, 9 H), 1.37-1.41 (m, 3 H), 1.23-1.36 (m, 1 H), 0.84-0.92 (m, 2 H), 0.54-0.60 (m, 2 H). LC/MS (m/z)=517 (M+H)+.
