The title compound was synthesized according to the procedure described for the synthesis of 6-tert-butylnicotinonitrile starting from 6-tert-butyl-2-methylnicotinonitrile (intermediate 31) (100 mg, 0.57 mmol), used crude from the above described description; MeMgBr 1.4 M 75/25 toluene/THF (1.4 ml, 1.4 mmol) and NaBH4 (55 mg, 1.4 mmol). Purified by normal phase chromatography with 20% MeOH/CH2Cl2. (Yield 31.5 mg, 29%). 1H NMR (400 MHz, CHLOROFORM-D) δ ppm 1.34 (s, 9 H), 1.36 (d, J=6.64 Hz, 3 H), 2.56 (s, 3H), 4.32-4.40 (m, 1 H), 7.15-7.19 (m, J=8.20 Hz, 1 H), 7.68 (d, J=8.20 Hz, 1 H).
