반응 단계
A reaction mixture of 3 g (14.11 mmol) of 2-chloromethyl-5-nitrobenzoxazole, 1.5 mL (17.97 mmol) of pyrrolidine, and 3.9 g (28.22 mmol) of potassium carbonate in 30 mL of DMF is stirred for 4 hours at 50° C. Then the reaction mixture is diluted with water and covered with diisopropyl ether, The precipitated yellow solid is suction filtered, washed again, and dried in the circulating air dryer at 60° C. Yield: 1.8 g (52% of theory); C12H13N3O3 (M=247.25); calc.: molecular ion peak (M+H)+: 248; found: molecular ion peak (M+H)+: 248; Rf value: 0.4 (silica gel, dichloromethane/ethanol (20:1)).
