Procedure

Using a method similar to Example 380, Part D, using 2-chloronicotinonitrile (1.00 g, 7.32 mmol), 2.0 M Al(CH3)3 in toluene (11 mL, 22.0 mmol) and methylamine hydrochloride (1.48 g, 22.0 mmol) gives the title compound (0.952 g, 76.7%): MS ES+ 171.8 (M+H)+, MS ES− 168.0 (M−H)−; HPLC [YMC-Pack Pro C-18 (150×4.6 mm, S-5 microm), 0.1% TFA/acetonitrile in 0.1% TFA/water at 1.0 mL/min, 5-95% over 19 min], tR=5.0 min, 97.0% purity.
