In a manner similar to Example 1, the reaction of 3-chloroaniline (38.3 g, 0.30 mole) with t-butyl nitrite (46.4 g, 0.45 mole) in the presence of copper powder (15.0 g, 0.24 mole) and 4Å molecular sieves (powdered, 15.0 g) in benzene (1650 ml) produced 3-chloro[1,1'-biphenyl] (38.4 g, 67.6% yield, bp 96°/0.15 mm) as an oil. When the experiment was repeated the yield was 65.7%
