A suspension of N-(5-fluoro-2-biphenylyl)thiourea (8 g) in water (40 ml) was reacted with a solution of potassium hydroxide (18.2 g) in water (40 ml), and a solution of lead acetate trihydrate (12.3 g) in water (70 ml). The reaction mixture heated at 90°-95° C. for 1 hour to give 5-fluoro-2-biphenylylcyanamide as a yellow oil.
