HCID 227603N-(4-chloro-2-methyl-6-quinolyl)acetamideYield 145.9%

Procedure

N-(4-Hydroxy-2-methyl-6-quinolyl)acetamide (4.32 g, 20 mmol) and phosphorus oxychloride (9.32 ml, 100 mmol) were heated at 100° C. for 15 min. The reaction mixture was cooled to room temperature and poured into ice water. Thereto was added 28% aqueous ammonia to make the solution alkaline. The resulting insoluble matter was collected by filtration, washed with ether and water, dried under reduced pressure at 80° C. to give N-(4-chloro-2-methyl-6-quinolyl)acetamide (6.85 g, crude, yellow solid).
