Procedure

15.5 g. (0.153 mol) of potassium nitrate was added portion-wise to a stirred solution of 33 grams (0.152 mol) of 4-(4-chlorobenzoyl)pyridine in 200 ml. of sulfuric acid while maintaining the temperature below 40° C. After one hour the mixture was cautiously poured into 2 liters of ice-water, neutralized with ammonium hydroxide and the product collected to yield 4-(3-nitro-4-chlorobenzoyl)pyridine as yellow prisms, mp. 114° -116° C. (cyclohexane-Norite).
