실험 절차
A mixture of tert-butyl 3-oxopiperazine-1-carboxylate (1500 mg, 7.49 mmol), 4-chloro-2-methoxy-1-nitrobenzene (1405 mg, 7.49 mmol),cesium carbonate (3417 mg, 10.49 mmol), (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (195 mg, 0.34 mmol) and TRIS(DIBENZYLIDENEACETONE)DIPALLADIUM (174 mg, 0.19 mmol)was dried for 15 min under HV. Degassed dioxane (17 ml) was added and the resulting mixture was stirred at 90°C for 16 hours under inert atmosphere. Work-up and purification: see EN02378-07-02. tert-butyl 4-(3-methoxy-4-nitrophenyl)-3-oxopiperazine-1-carboxylate (2640 mg, 100 %) was isolated as an orange foam. FLA 02378-10-01: 1H NMR, LC-MS: OK.
