Versuchsvorschrift

A suspension of 2-bromomethyl3-methylnaphthalene (2.87 g, 12.2 mmol) and NaCN (652 mg, 13.3 mmol) in CH3CH/H2O (9:1, 125 mL) was heated to reflux for 1 hour. Upon warming, the suspension became homogeneous. After cooling to room temperature, the volatiles were removed from the reaction mixture in vacuo and the residue was partitioned between 2O (150 mL) and CH2Cl2 (150 mL). The aqueous phase was extracted with CH2Cl2 (1×150 mL). The combined organic layers were dried (Na2SO4) and concentrated in vacuo to give the title compound as a white solid (2.18 g, 99%). This material was of sufficient purity to be used as such in the next step.
