Reaction Steps

Into a 50-mL round-bottom flask, was placed benzaldehyde (4 g, 37.69 mmol, 1.00 equiv), propanedinitrile (3.3 g, 49.95 mmol, 1.30 equiv), n-butanol (10 mL), piperidine (1 mL). The resulting solution was stirred for 16 h at 20° C. The resulting mixture was concentrated under vacuum. The resulting mixture was washed with 1×33 mL of H2O/EtOH(10/1). The solids were collected by filtration. The solid was dried in an oven. This resulted in 4.2 g (69%) of 2-(phenylmethylidene)propanedinitrile as a yellow solid.
