Procedure

2-(Dihydro-2H-pyran-4(3H)-ylidene)-2-(6-(trifluoromethyl)pyridin-3-yl)acetonitrile (1.04 g, 3.88 mmol) was dissolved in methanol (50 mL) and 7 M NH3 in methanol (20 mL) was added. The solution was flushed with Ar. Raney nickel (0.033 g, 0.39 mmol) was added and mixture hydrogenated on a Parr Apparatus at room temperature for 4 hours. Then filtered through a plug of celite and concentrated in vacuo. The crude product was used for the next step without further purification.
