Versuchsvorschrift

A suspension of N-(5-methyl-2-biphenylyl)thiourea (6.5 g) in water (50 ml) was reacted with a solution of potassium hydroxide (15 g) in water (50 ml). Lead acetate trihydrate (10.2 g) in water (50 ml) was added and the mixture heated at 90°-95° C. for 1 hour to give 5-methyl-2-biphenylylcyanamide as a colourless solid (m.p. 80° C.).
