실험 절차

Sodium hydride (1.54 g, 64.1 mmol) dissolved in DMF (15 ml) and cooled to 0° C. Phenyl acetonitrile (3 g, 25.6 mmol) and 1,3-dibromopropane (5.2 g, 25.6 mmol) were dissolved in DMF (15 ml) and added to above mixture drop-wise at 0° C. This mixture was heated to rt and continued stirring for 2 h. Work up (H2O/Toluene) afforded the title compound (2.61 g) as crude, which was used in the next without further purification.
