To a solution of 3-(2-chlorophenyl)-3-[(3-methylbutan-2-yl)amino]acrylonitrile (1 g, 4.02 mmol, 1 eq.) in 1,2-dichloroethane (2 ml) were added cyclopropylacetyl chloride (1.71 g, 16.08 mmol, 4 eq.) and pyridine (1.58 g, 20.1 mmol, Seq.) and the solution was heated to 80° C. for 8 h. The reaction was quenched with 1N aq. HCl (20 ml) and extracted with ethylacetate. The organic layers were combined and washed with 1N aq. NaOH (20 ml), dired over MgSO4 and concentration under vacuum. The residual oil was subjected to column chromatography to give 2-{(2-chlorophenyl)[(3-methylbutan-2-yl)amino]methylene}-3-oxohexanenitrile (1.012 g, 75% yield).
