Some novel (2) Ammonium thiocyanate (2. (ESI): Calcd. for [M ? H]? C16H18Cl3N2O9S1: 518.9799, Found 518.9794. 3.2.2. (4) To a remedy from the isothiocyanate intermediate 2 (5.00 g, 9.58 mmol) in dried out acetonitrile (30 mL), sulfonamide 3 (3.30 g, 19.16 mmol) was added and stirred at 50 C for 4 h. The blend was cooled to area temperature, focused, and diluted with ethyl acetate. The organic level was cleaned with aqueous hydrochloric acidity (1N), saturated PRI-724 supplier aqueous sodium brine and bicarbonate, dried out over anhydrous sodium sulfate, filtered, focused, and purified by column chromatograph (100:1, dichloromethaneCmethanol) to cover substance 4 (6.20 g, 93.23%) being a white good; m.p. 159.2C161.1 C; 1H-NMR (600 MHz, DMSO-10.23 (s, 1H), 8.35 (s, 1H), 8.11 (d, = 9.4 Hz, 1H), 7.75 (d, = 8.6 Hz, 2H), 7.68 (d, = 7.8 Hz, 2H), 7.30 (s, 2H), 5.72 (s, 1H), 5.21 (t, = 9.8 Hz, 1H), 4.90C4.83 (m, 3H), 4.21 (dd, = 12.4, 4.6 Hz, 1H), 3.97 (d, = 12.0 Hz, 1H), 3.82 (q, = 9.8 Hz, 1H), 3.76 (s, 1H), 1.99 (s, 3H), 1.98 (s, 3H), 1.92 (s, 3H); 13C-NMR (100 MHz, DMSO-181.86, 170.03, 169.39, 154.62, 141.92, 139.37, 126.24, 122.13, 96.21, 73.30, 73.09, 72.20, 68.56, 61.74, 54.20, 20.56, 20.43, 20.41; HRMS (ESI): Calcd. for [M + H]+ C22H28Cl3N4O11S2: 693.0262, Found 693.0256. 3.2.3. General Process of the formation of Substances 7aC7r To an PRI-724 supplier assortment of 4 (500 mg, 0.72 mmol) in acetone (10 mL), freshly activated zinc natural powder (1.65 g, 25.22 mmol) and acetic acidity (10 mL) were added and stirred PRI-724 supplier for 1 h. The residue was filtered, focused, and diluted with ethyl acetate. The organic level was cleaned by saturated aqueous sodium brine and bicarbonate, dried over anhydrous sodium sulfate, filtered, and concentrated in vacuo. The white solid product 5 was directly utilized for the next step without further purification. To a solution of crude 5 from your last step in dry pyridine (10 mL) WNT16 at 0 C, substituted sulfonyl chloride (0.79 mmol) was dropped into the combination slowly, and the reaction was stirred for 10 min at room temperature. After total consumption of the starting material, the residue was diluted with ethyl acetate and washed with aqueous hydrochloric acid (1M), saturated aqueous sodium bicarbonate, and brine. The solution was dried over anhydrous sodium sulfate, filtered, and concentrated. The light yellow oily product 6aC6r was directly utilized for the next step without further purification. To a solution of intermediate 6aC6r in acetoneCmethanol (5 mL:5 mL), freshly prepared sodium methoxide in methanol answer (1.0 mol/L, 1 mL) was added. The combination was stirred for 30 min followed by the addition of Dowex H+ resin to pH 7, then filtered. The filtrate was concentrated and purified by column chromatograph (10:1, dichloromethaneCmethanol) to obtain 7aC7r.
