Reaction Steps
To a stirred mixture of cyanoacetamide (2.5 g, 0.030 mol) and tetrahydrofuran (160 mL) is slowly added potassium tert-butoxide (3.3 g, 0.030 mol) followed by p-chlorophenacyl bromide (7.0 g, 0.030 mol). The reaction is slightly exothermic and, after a short time, TLC shows none of the p-chlorophenacyl bromide present. The reaction mixture is diluted with water and brine and extracted with ether. The ether extract is dried and concentrated in vacuo to give a red oil. Upon addition of a hexane/ethyl acetate mixture (3:1) to the oil a solid forms and is collected by filtration to give the title product as a light yellow solid (1.4 g, 20%, mp 160°-161° C.) which is identified by IR and NMR spectral analyses.
