実験手順

The title compound was synthesized according to the procedure described for the synthesis of [1-(6-tert-butylpyridin-3-yl)ethyl]amine starting from 6-tert-butyl-2-chloronicotinonitrile (intermediate 22) (2.0 g, 10.3 mmol), MeMgBr (18 ml, 25.7 mmol) and NaBH4 (970 mg, 25.7 mmol). The resulting material was used crude in the following coupling step. (Yield: 1.76 g, 79%) 1H NMR (400 MHz, CDCl3) δ ppm 1.34 (s, 9 H) 1.39 (d, J=6.64 Hz, 3 H) 4.47 (q, J=6.64 Hz, 1 H) 7.26 (d, J=8.01 Hz, 1 H) 7.78 (d, J=8.01 Hz, 1H).
