실험 절차

N-Phthaloylglycine (90.7 g, 442 mmol) was dissolved in portions (because of clumping) in DMF (500 mL). 1,1′-Carbonyldiimidazole (78.9 g, 486 mmrol) was added in portions (attention CO evolution). The resulting suspension was heated at 80° C. for 20 min. and then cooled to rt, then cyclopropanecarboxamidoxime 1 added and then heated at 110° C. for 2 h. The solution was cooled to rt, then poured into water (4 L), stirred for 15 min, filtered, washed with water (400 mL) and (fried. Yield: 104 g (87%). Mp 115° C. m/z 269 (M).
