Methyl styrylcarbamate

Phenylacetaldehyde. An alkaline solution of sodium hypochlorite is prepared by passing 55 g. of chlorine into a mixture of 600 g. of cracked ice and a cold solution of 100 g. of sodium hydroxide (95%) in 150 cc. of water. Water is then added until the total volume of the solution is 11. (The solution is best kept in the dark until used.) To a solution of 14.7 g. (0.1 mole) of cinnamic amide (m.p. 147°) in 125 cc. of methanol is added 130 cc. of the stock solution of sodium hypochlorite. The mixture is warmed on the water bath. A thick sludge of crystals soon forms. The mixture is cooled rapidly and filtered, and the crystals are washed with dilute ethanol and with water. The yield of methyl styrylcarbamate so obtained is 13 g. (70%), m.p. 117-118°.
