PROCEDURE
实验过程
1-Phenyl-1-cyclopropanecarbonitrile (1.0 g, 6.98 mmol) was added to a stirred suspension of lithium aluminum hydride in anhydrous diethyl ether (25 mL). The suspension was refluxed for 2 h, then cooled to 0° C., and the excess hydride was destroyed by careful addition of water. After treatment with sodium hydroxide (1 N), the mixture was filtered and the filtrate extracted with diethyl ether. After drying of the organic phase with and evaporation 2 (719 mg, 70% ) was obtained as a clear liquid and used without further purification. 1H NMR (DMSO-d6): δ 7.28 (m, 4 H), 7.17 (m, 1 H), 2.70 (s, 2 H), 1.45 (bs, 2 H); 0.78 (dd, J=6.2, 3.8 Hz, 2 H); 0.67 (dd, J=6.2 Hz, 3.8 Hz, 2 H). MS: (m/z) 148 (M+1)+.
