To a solution of 1-phenylcyclopropanecarbonitrile (50 g, 0.34 mol, 1 eq.) in tetrahydrofuran (500 mL, 0.7 M) at 0° C. was added lithium aluminum hydride (23 g, 0.35 mol, 1.03 eq.). The reaction mixture was stirred at 0° C. for one hour and then at reflux for one hour. The reaction mixture was then cooled down and quenched with water (23 mL) and a 15% aqueous sodium hydroxide solution (69 mL). The mixture was filtered and concentrated in vacuo to afford #*1 (36 g, 72%). LC-MS: m/z 148.1 [M+H+], retention time=0.86 minutes; 1H NMR (400 MHz, CDCl3) δ 7.2-7.4 (m, 5H), 2.78 (s, 2H), 1.19 (br s, 2H), 0.72-0.84 (m, 4H).
