HCID 20061086HCID 20061086, compound

Procedure

15.5 g. (0.153 mol) of potassium nitrate was added portionwise to a stirred solution of 33 g. (0.152 mol) of 2-(4-chlorobenzoyl)pyridine in 200 ml. of sulfuric acid, while maintaining the temperature below 40° C. After 1 hour the mixture was cautiously poured into 2 liters of ice water and neutralized with ammonium hydroxide. The resulting product 2-(3-nitro-4-chlorobenzoyl)pyridine was collected as white microneedles, mp. 98° -99° C. (cyclohexane).
