90% | With sodium carbonate;tetrakis(triphenylphosphine) palladium(0); In 1,2-dimethoxyethane; water; at 100℃; for 16h; | EXAMPLE 2 4-Amino-l -(7H-pyrrolo['2,3-d1pyriniidin-4-ylVpiperidine-4-carboxylic acid (6- chloro-biphenyl-3-ylmethylVamide hydrochloride2A. 2-Chloro-5-methyl-biphenylA mixture of 2-bromo-l-chloro-4-methyl-benzene (4.83 g, 23.4 mmol), benzeneboronic acid (5.7 g, 46.7 mmol), Pd(Ph3P)4 (1.35 g, 1.2 mmol) and 2M Na2CO3 (34 mL) in DME (100 mL) was stirred at 1000C under N2 for 16 h. After cooling, the resulting suspension was filtered. The filtrate was diluted with saturated brine and extracted with ethyl acetate (2 x 150 mL). The combined organic layers were washed with brine (100 mL) and water (100 mL), dried (Na2SO4) and filtered through decolourising charcoal. After evaporation of the solvent, n-hexane was added to the oil. The mixture was filtered to remove solids and the filtrate was concentrated. The resulting crude oil was purified by silica column chromatography (ethyl acetate : n-hexane / 1 : 20) to give the title <n="90"/>compound (1.76g, 90 %) as a light yellow oil. Rf= 0.55.

With sodium hydrogencarbonate;tetrakis(triphenylphosphine) palladium(0); In water; N,N-dimethyl-formamide; at 120℃; for 0.0833333h;Microwave irradiation; | Example 7: 4-(2'-Chloro-5'-methyl-biphenyl-4-ylmethyl)-2-phenyl-morpholine; 109mg of 4-(4-Bromo-benzyl)-2-phenyl-morpholine was combined with 102mg of bis(pinacolato)diboron, 97mg of potassium acetate, l lmg tetrakis(triphenylphosphine)palladium(0), and 1.9mL DMF. The mixture was heated in a microwave reactor at 12O0C for 7 minutes and cooled. 0.8mL of 2M aqueous sodium bicarbonate was added along with lOlmg of <strong>[57310-39-1]3-Bromo-4-chlorotoluene</strong> in 0.15mL DMF. The mixture was heated in the microwave reactor for an additional 5 minutes at 120C. The <n="25"/>reaction was cooled and filtered through Celite, washing with methylene chloride. The eluant was concentrated and purified by flash chromatography twice using an ethyl acetate/hexanes gradient to afford 3.5mg of product. ES MS (+) m/z 378 |

51% | With N,N-dimethyl acetamide; palladium diacetate; potassium carbonate; tricyclohexylphosphine; Trimethylacetic acid; at 150℃; for 10h;Inert atmosphere; | In a reactor equipped with a reflux condenser, a mixture of 3-bromo-4-chlorotoluene (compound CM20a above, 30.82 g, 150 mmol), 2,5-dimethylphenylboronic acid (compound CM20b above, 24.75 g, 165 mmol), anhydrous potassium carbonate (124.39 g, 900 mmol), palladium(II) acetate (0.67 g, 6 mmol), tricyclohexylphosphine (1.68 g, 12 mmol), dimethylacetamide (commercially available dehydrated product, 600 ml) and pivalic acid (15.32 g and 150 mmol) was stirred for 10 hours under an argon gas atmosphere while heating in an oil bath set to 150 C. After diluting with toluene (500 ml), rinsing and liquid separation were carried out 3 times using ion-exchanged water. Next, there was repeated twice a procedure of adding active white clay (product of Wako Pure Chemical Industries, Ltd., 60 g) to the obtained oil layer, stirring the mixture for 2 hours, and then passing it through Celite and a silica gel pad to remove the insolubles. After removing the solvent from the obtained solution by concentration under reduced pressure, recrystallizing purification was carried out (with a mixed solvent of chloroform and ethanol), and the deposited crystals were filtered out and dried under reduced pressure to obtain the target CM20c (35.5 g) as a solid with a faint yellow-white appearance. Yield: 51%. The HPLC-area percent value of the obtained compound CM20c measured under analysis conditions 1 was 99.3% (UV254 nm) |

47% | With N-Bromosuccinimide; 2,2'-azobis(isobutyronitrile); In tetrachloromethane; for 4h;Reflux; | Step 1: <strong>[57310-39-1]3-Bromo-4-chlorotoluene</strong> (1.0 equiv, 3.0 g, 14.6 mmol) and N-bromosuccinimide (1.2 equiv., 3.1 g, 17.5 mmol) were dissolved in CCl4, AIBN (0.01 equiv., 23.9 mg, 0.15 mmol) was added and the mixture was stirred under reflux for 4 h. After cooling to room temperature, the mixture was washed with sat. NaHCO3 solution and with water, the organic phase was concenrtated and the residue was purified by column chromatography (EtOAc/heptane gradient). This gave 2.0 g (47% of theory) of 2-bromo-4-bromomethyl-1-chlorobenzene. |
With N-Bromosuccinimide; 2,2'-azobis(isobutyronitrile); In tetrachloromethane; for 16h;Reflux; | General procedure: A mixture of bromotoluene intermediate 7-14 or 16 (10 mmol), N-bromosuccinimide (15 mmol, 2.67 g) and azobisisobutyronitrile (5 mmol, 82 mg) in tetrachloromethane (20 mL) was refluxed for 16 h. After cooling the mixture was filtered, the filtrate was diluted with dichloromethane (30 mL), washed with water (50 mL) and brine (50 mL), dried over anhydrous Na2SO4 and evaporated. The residue containing the adequate benzyl bromide derivative without further purification was used to the next step. |
