With potassium carbonate In 1-methyl-pyrrolidin-2-one at 80℃; |
To a solution of 5-bromo-2-chloropyrimidine (1.02 g) in N-methylpyrrolidine-2- one (10 mL) was added lH-imidazole (680 mg) and potassium carbonate (2.74 g) and refluxed overnight at 80 0C. The reaction mixture was poured in water and extracted with dichloromethane, washed with brine and dried over anhydrous sodium sulfate. Solvent was removed under vacuum and to the product thus obtained was added cold ethanol which afforded the title compound (200 mg).EIMS (m/z): 225 (M+H) |

Stage #1: 1H-imidazole With sodium hydride In dimethyl sulfoxide at 20℃; for 0.166667h;
Stage #2: 5-Bromo-2-chloropyrimidine In dimethyl sulfoxide for 1h; |
D1
D1. 5-Bromo-2-imidazol-1-yl-pyrimidine; 280 mg of sodium hydride (strength 60 Vol%) are suspended in 5.0 ml of DMSO under an atmosphere of dry nitrogen. Subsequently, a solution of 409 mg of imidazole in 5.0 ml of DMSO is added dropwise at room temperature. After the gas evolution has ceased, the reaction mixture is stirred for further 10 min. Thereafter, a solution of 987 mg of 5-bromo-2-chloro-pyrimidine in 10 ml of DMSO is added dropwise to the reaction mixture. The yellow suspension is stirred for 1 hour. For workup, the reaction mixture is poured into 150 ml of iced water and the suspension is filtered with suction. The residue is rinsed with water and dried to yield 1.11 g of the title compound as a colorless solid. M. p. 2260C. ESI- MS: 225.2/227.2 (MH+). TLC: Rf = 0.50 (dichloromethane/methanol 20:1 parts per volume). |

C1
C1. 1-(4-Bromo-phenyl)-1-(2-imidazol-1-yl-pyrimidin-5-yl)-methanol; 22.5 g of 5-bromo-2-imidazol-1-yl-pyrimidine (compound D1 ) are dissolved in 250 ml of tetrahydrofuran under an atmosphere of dry nitrogen. Subsequently, the reaction mixture is cooled in an ice bath and 70 ml of isopropylmagnesium chloride (strength 2.0 M in tetrahydrofurane) are added dropwise. Thereafter, the solution is allowed to warm up to room temperature and stirred for 30 min.Subsequently, a solution of 14.8 g of 4-bromo-benzaldehyde in 50 ml of tetrahydrofurane is added dropwise and stirring is continued for 48 hours. For workup, the reaction mixture is poured into 300 ml of water. The solution is subsequently acidified to pH 5 using hydrochloric acid (strength 1.0 N), extracted three times with each 100 ml of dichloromethane, dried using Na2SO4, filtered with suction, and evaporated to dryness. The remaining crude material is purified by flash chromatography (eluent gradient: dichloromethane/ethanol 0.0-5.0 Vol%) to afford 11.19 g of the title compound as a colorless solid. M. p. 2270C. ESI-MS: 331.3/333.2 (MH+). TLC: Rf = 0.29 (dichloromethane/ethanol 20:1 ). |

Copper-Catalyzed C-N Bond Exchange; General Procedure
General procedure: The 2-substituted 5-halopyridine or 5-halopyrimidine substrate (0.5 mmol), an N-heterocyclic amine (1.0 mmol), Cu(NO3)2 (0.1 mmol) and Cs2CO3 (1.0 mmol) were added to a 25-mL Schlenk tube, followed by addition of DMF (2 mL). This mixture was stirred at 130 °C or 140 °C (see schemes and tables) under air atmosphere for 24 h. Then, the reaction mixture was added to brine (15 mL) and this mixture was extracted with CH2Cl2 (3 × 15 mL). The combined extracts were concentrated under reduced pressure and the product was isolated by flash chromatography on a silica gel (200-300 mesh) column. |

With bis-triphenylphosphine-palladium(II) chloride; potassium phosphate; In 1,4-dioxane; water; at 95℃;Inert atmosphere; |
General procedure: The halo aryl (1.0 equiv) was dissolved in a mixture of water:dioxane (1:1). The boronic acid or ester(1.5 equiv) and potassium phosphate (5.0 equiv) were added. The solution was degassed byvacuum/argon cycles (10 times) before addition of PdCl2(PPh3)2 (10 mol%) and further degassed (5times). The resulting mixture was stirred at 95 C under argon atmosphere for 16-20 hours. Thereaction mixture was filtered through Celite and diluted with water (approx. 30 mL) before washingwith chloroform (3 x 30 mL). If not stated otherwise, the aqueous phase was concentrated underreduced pressure and applied to a C18 precolumn before purification on a 10g or 60 g C18 column witha gradient of acetonitrile in water (10-100%) to yield the desired product. |
