反应条件: temp:0.00; pressure:0.00; stir:

反应条件: temp:80.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Prepared according to the method described in Example 12) from (1S,2R)-4-(2-hydroxy-1-methyl-4-pyridin-3-ylbutoxy)benzeneboronic acid (0.2 g, Example 33), 4-bromo-2,5-difluorobenzenesulfonamide (0.19 g, Example 37a)), ethanol (3 ml), 2M aqueous sodium carbonate (0.7 ml) and tetrakis(triphenylphosphine)palladium (0) (0.03 g) with heating at 80° C. for 3 hours. After work-up, the residue was purified by normal-phase HPLC eluting with a gradient of 0-25% ethanol in dichloromethane to give the title compound as a foam (0.11 g). Prepared After work-up, the residue was purified by normal-phase HPLC eluting with a gradient of 0-25% ethanol in dichloromethane

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Ammonium hydroxide (5 ml) was added to a solution of 2,5-difluoro-4-bromophenylsulfonyl chloride (4.3 g) in tetrahydrofuran (20 ml) at room temperature (CARE:exotherm) and stirred for 10 min. The reaction mixture was poured into water and extracted with ethyl acetate. The ethyl acetate was dried over anhydrous magnesium sulfate and filtered. The filtrate was evaporated and the residue triturated with 20% diethyl ether in isohexane to give the sub-title compound as a solid (4.3 g). extracted with ethyl acetate The ethyl acetate was dried over anhydrous magnesium sulfate filtered The filtrate was evaporated the residue triturated with 20% diethyl ether in isohexane
