With tetrakis(triphenylphosphine) palladium(0); sodium carbonate; In ethanol; water; toluene; at 65.0℃; for 1.0h;Inert atmosphere; | General procedure: To a solution of Intermidiate-1 (1 g, 1.781 mmol), methyl 3-(4,4,5,5-tetramethyl-l ,3,2- dioxaborolan-2-yl)benzoate (0.467 g, 1.781 mmol) and sodium carbonate (0.321 g, 5.34 mmol) in ethanol (5 mL), toluene (5 mL) and water (2 mL) bubbled the nitrogen for 30 minutes. Tetrakis(triphenylphosphine)palladium(0) (23 mg, 0.089 mmol) was added to the reaction mixture and again nitrogen was bubbled for 10 minutes. The reaction mixture was then heated to 65 °C and further maintained for lh. Reaction was monitored by TLC. The resulting solid was removed by filtration through celite bed. The filtrate was extracted with ethyl acetate (2 x 25 mL) and washed with water (15 mL) and brine solution (15 mL). The organic layer was dried over sodium sulfate and concentrated under reduced pressure to get crude compound. This crude compound was further purified by flash chromatography (Biotage) (ethyl acetate: hexane=l :20) to give title compound (660 mg, 67.7percent) m/z 548.57. The title compound was prepared by following the similar procedure as described Step-i to Step-3 of Example-i in sequential manner by taking Intermediate-3 and (3- (methoxycarbonyl)-4-methylphenyl)boronic acid.The two diastereomers were separated by chiral preparative HPLC [CHIRAL PAK ID, 250mm x 4.6,5ji; A=n-hexane IPA (90/10 percentv/v, 0.1 percentDEA), B=IPA; A:B=90/10 percentv/v;Flow = 1.0 mllmin] Isomer ?a?: tR = 6.05, Isomer ?b?: tR = 6.62; m/z, 461.9.

The mixture was degassed for 15 mm and then, PdC12 (dppf) (5mol percent) was added. The reaction mixture was heated to 80°C overnight. TLC showed complete conversion of starting material so it was filtered through a pad of celite and concentrated to give the crude product that waspurified by column chromatography (10percent Ethyl acetate-Hexanes) to give the desired compound (50-60 percent). |

65% | With tetrakis(triphenylphosphine) palladium(0); sodium carbonate; In 1,4-dioxane; at 90.0℃; for 4.0h;Inert atmosphere; | To an oven-dried round-bottomed flask was added Intermediate-2 (100 mg, 0.329 mmol), [3- (methoxycarbonyl)-4-methylphenyl] boronic acid (63.8 mg, 0.329 mmol) in anhydrous dioxane (10 ml) under N2 atmosphere. A degassed aqueous solution of sodium carbonate (105 mg, 0.986 mmol) was then added via syringe to the vigorously stined reaction mixture, followed by tetrakis(triphenylphosphine)palladium (0) (18.99 mg, 0.0 16 mmol). The reaction mixture was stirred at 90°C for 4 h. TLC showed completion of reaction. The reaction mixture was diluted with water (25 ml) and ethyl acetate (25 ml). The phases were separated and the aqueous phase was extracted with ethyl acetate (2 x 15 ml). The combined organic extract was washed with water (2 x 25 ml), brine (50 ml) and dried over anhydrous sodium sulphate, filtered and concentrated in vacuo to get 0.2g of the crude residue. The crude compound was purified by column chromatography over silica gel (100-200 mesh) with isocratic elution of 20 percent ethyl acetate in hexane to afford title compound ( mg, 65percent) as a off white solid. ?H NMR (400 MHz, CDC13-d6) oe 10.22 (s, 1H), 8.39 (s, 1H), 8.11-8.07 (m, 2H), 7.93-7.90 (m, 2H), 7.64-7.62 (m, 2H), 7.56-7.54 (m, 1H), 7.42 (d, J =7.6 Hz, 1H), 3.91 (s, 3H), 2.72 (s, 3H); MS (ES+) mlz = 304.54. |

Subsequently, 1, 1-bis(diphenylphosphino)ferrocenedichloropalladium(II) (117 mg, 0.16 mmol) was added and the mixture was stirred at 140° C. in a microwave for 1 h. At RT, the reaction mixture was then diluted with 50 ml of water, acidified with 1M hydrochloric acid and extracted twice with 70 ml each time of ethyl acetate. The combined organic phases were washed once each with water and saturated aqueous sodium chloride solution, dried over sodium sulphate and filtered, and the filtrate was concentrated. The residue obtained was taken up in ethyl acetate, and the precipitate formed was filtered off, washed with ethyl acetate and dried under high vacuum. The crude product obtained in this manner (82percent pure) was reacted further without further purification. LC-MS (Method 1): Rt=1.14 min; MS (ESIpos): m/z=696 [M+H]+. |
