46%Spectr.; 39%Spectr. | With nickel; hydrogen; In tert-butyl alcohol; at 70℃; under 760.051 Torr; for 16h; | General procedure: To a suspension of 0.4 g (0.012 mol) of sodium borohydride in 20 mL of piperidine 6a at 30C was added 0.8 g (0.006 mol) of anhydrous nickel(II) chloride. The mixture was heated to 60C to produce black colloid solution of a catalyst. Butyronitrile (6.9 g, 0.1 mol) was added to the resulting catalyst, and hydrogen was passed at 70C for 14 h. After cooling, 1 mL of water was added to the mixture to accelerate the catalyst coagulation. The precipitate was filtered off, the filtrate was analyzed.
