반응 단계
To a mixture of 4′-chloro-2-hydroxyacetophenone (3.41 g), potassium cyanate (3.25 g) and isopropanol (15 mL) was added dropwise acetic acid (2.88 g) at 50° C. The obtained mixture was stirred at 50° C. for 5 h and water (34 mL) was added. The precipitated crystals were collected by filtration, and washed with water and then with isopropyl ether to give 4-(4-chlorophenyl)-2-oxo-4-oxazoline (3.33 g; yield 85.1%).
