실험 절차

A solution of 3-(7-bromo-4-methyl-3-oxo-2,3,4,10-tetrahydro-9-oxa-1,2,4a-triaza-phenanthren-6-ylamino)-azetidine-1-carboxylic acid tert-butyl ester (Example #1, Step B, 0.1 g, 0.21 mmol), aniline (0.06 g, 0.64 mmol), Pd2(dba)3 (0.039 g, 0.04 mmol), Xantphos (0.0496 g, 0.09 mmol), and Cs2CO3 (0.14 g, 0.43 mmol) in anhydrous dioxane (10 mL) was heated at 130° C. for 14 h. The reaction mixture was cooled to ambient temperature and concentrated in vacuo, The residue was purified by chromatography on silica gel (eluting with 50% EtOAc in petroleum ether) to give 3-(4-methyl-3-oxo-7-phenylamino-2,3,4,10-tetrahydro-9-oxa-1,2,4a-triaza-phenanthren-6-ylamino)-azetidine-1-carboxylic acid tert-butyl ester (0.014 g, 14%) as brown solid. LC/MS (Table 1, Method 2) Rt=1.205 min; MS m/z: 542 [M+23+41]+
