Procedure
Benzonitrile (5.2g) was added dropwise to a solution of 1,1,1-trichloro-2-hydroxy-2-(chloroacetamido)ethane (12.05g) in concentrated sulphuric acid (50 ml). The temperature was kept at 0° during the addition. The mixture was stirred at room temperature for 4 hours, then left overnight. The reaction mixture was poured on to ice. The precipitated solid was collected, washed with water and dried (19.6g). Recrystallisation from nitromethane gave pure 1,1,1-trichloro-2-benzamido-2-(chloroacetamido)ethane (14.6g, m.p. 210°-12°)
