실험 절차

To a stirred solution of (3-methyl-2-naphthalenyl)acetonitrile (2.17 g, 12 mmol) in dry THF (125 mL) cooled to -78° C. was added n-BuLi (8.44 mL, 13.5 mmol; 1.6M solution in hexanes)dropwise over 10 minutes. The resulting orange solution was stirred for 20 minutes at -78° C. and MeI (1.92 g, 13.5 mmol) was added in one portion. The reaction mixture was stirred at -78° C. for 1.25 hours and quenched with saturated NH4Cl (20 mL). After warming to room temperature, the volatiles were removed in vacuo and the residue was diluted with H2O (150 mL). The aqueous phase was extracted with Et2O (2×150 mL). The combined organic layers were washed with saturated NaCl (1×150 mL) and dried (MgSO4). Removal of the solvent in vacuo afforded the product as a light yellow solid (2.34 g, 100%). This material was of sufficient purity to be used as such.
