YieldReaction ConditionsOperation in experiment
With potassium phosphate;tetrakis(triphenylphosphine) palladium(0); In N,N-dimethyl-formamide; at 120℃; for 1h;Inert atmosphere; Microwave irradiation; A microwave reactor is charged with 1-methyl-indole-2-boronic acid (1.18 g, 6.78 mmol), (3-bromo-pyridin-4-yl)-methanol (0.850 g, 4.52 mmol), potassium phosphate (1.91 g, 9.04 mmol) and DMF (10 ml_). The reactor is evacuated and filled with nitrogen thrice and Pd(PPh3)4 (0.261 g, 0.226 mmol) is added. The reactor is evacuated and filled with nitrogen thrice again. The mixture is heated to 120 C for 1 h under microwave irradiation, then diluted with ethyl acetate and washed with water thrice. The organic layer is dried over sodium sulfate and concentrated in vacuo to give a residue which is purified by silica gel flash chromatography (dichloromethane-methanol, 19:1 ) to afford [3- (1-methyl-1 H-indol-2-yl)-pyridin-4-yl]-methanol as a white solid. 1H NMR (400 MHz, MeOD) δ ppm 3.58 (s, 3 H), 4.57 (s, 2 H), 6.54 (s, 1 H), 7.14 (t, J=7.5 Hz, 1 H), 7.27 (ddd, J=7.6, 1.1 Hz, 1 H), 7.46 (d, J=8.3 Hz, 1 H), 7.62 (d, J=7.8 Hz, 1 H), 7.81 (d, J=5.1 Hz, 1 H), 8.49 (s, 1 H), 8.67 (d, J=5.1 Hz, 1 H).

YieldReaction ConditionsOperation in experiment
69% To a stirred solution of (3-bromopyridin-4-yl)methanol (2.377 g, 12.64 mmol) and triethylamine (3.52 mL, 25.28 mmol) in dichloromethane (52.6 mL) was added a solution of methanesulfonyl chloride (1.034 mL, 13.27 mmol) in dichloromethane (5.26 mL) at 5° C.-10° C. When the addition was completed the mixture was stiffed at 5° C.-10° C. for 2 hours, treated with acetonitrile (52.6 mL), and then the dichloromethane evaporated in vacuo to leave a solution of the mesylate in acetonitrile, which was treated with <strong>[4983-28-2]2-chloropyrimidin-5-ol</strong> (1.500 g, 11.49 mmol) and potassium carbonate (4.76 g, 34.47 mmol) and the stirred mixture heated under reflux at 85° C. overnight. The mixture was cooled to ambient temperature and the acetonitrile evaporated in vacuo to a residue which was partitioned between water (50 mL) and ethyl acetate (100 mL), and filtered through a filtration aid. The ethyl acetate layer washed with brine, dried (MgSO4) and evaporated in vacuo to a residue which was chromatographed on silica with 50percent ethyl acetate in isohexane as eluant to give a solid which was crystallised from ethyl acetate/isohexane to give 5-((3-bromopyridin-4-yl)methoxy)-2-chloropyrimidine (2.370 g, 69percent). 1H NMR (400.13 MHz, CDCl3) 5.1 (2H, s), 7.4 (1H, d), 8.3 (2H, s), 8.5 (1H, d), 8.7 (1H, s). m/z (ES+) (M+MeCN)+=343.
