Reaktionsschritte
Borane-dimethyl sulfide complex (14.30 mL, 14.30 mmols) was added to tetrahydrofuran solution of 2-chloroisonicotinic acid (17.56 g, 11.5 mmols) under cooling with ice, and stirred at room temperature for 2.5 days, followed by further an hour's stirring at 50° C. Cooling the reaction liquid to room temperature, ethyl acetate was added, followed by washing with saturated aqueous ammonium chloride solution and saturated brine and drying over anhydrous sodium sulfate. Concentrating the solvent under reduced pressure, the tide compound (15.0 g, 93%) was obtained.
