Reaction Steps
To a suspension of 4-chloroaniline (21.14 g, 0.166 mol) in water (156 ml) and 12N HCl (46 ml) at 0° was added sodium nitrite (12.62 g, 0.182 mol) in water (156 ml) over 20 minutes keeping the reaction temperature below 10°. The solution of 4-chlorobenzenediazonium chloride was filtered, kept at 0° for 30 minutes and then used in the next step.
