Reaction Steps

To a solution of 2-pyridinecarbonitrile (1.00 g, 9.60 mmol) in ether (30 mL) were added successively at RT titanium tetraisopropoxide (3.1 mL, 10.0 mmol) and 1.0 M of ethylmagnesium bromide in tetrahydrofuran (19 mL). After the mixture was stirred for 30 min, water (5.0 mL) was added. The mixture was extracted with diethyl ether. The combined organic layers were washed with brine, dried over MgSO4, filtered, and concentrated to afford the crude product which was directly used in the next step without further purification.
