Reaction Steps

Based on Kulkarni, N. R. Ayyangar, Tetrahedron, 1994, 50, 1243–1260. ]: A mixture of 3-bromopropiophenone (10.65 g, 50 mmol), CuCN (5.82 g, 65 mmol) in DMF (35 mL) was heated under reflux for 6 h. After cooling the mixture to ambient temperature FeCl3 (5 g) in H2O (30 mL)/HCl conc (10 mL) was added and heated to 80° C. for another 20 min. After cooling to room temperature and extraction with ether further purification occurred by destination under reduced pressure (bp.: 140° C., 10 torr). The ketone could be obtained as slightly yellow, low melting (42° C.) solid.
