실험 절차
To a solution of 2-(7-methyl-6-nitro-3-thioxo-2,3-dihydro-benzo[1,4]oxazin-4-yl)-propionic acid ethyl ester (0.130 g, 0.40 mmol) in EtOH (8 mL) was added hydrazine hydrate (98%, 1.4 mmol, 0.070 g) and the reaction mixture was heated at 120° C. for 4 h. The reaction mixture was cooled to ambient temperature and the solvent was removed in vacuo to give 4,7-dimethyl-6-nitro-2,10-dihydro-9-oxa-1,2,4a-triaza-phenanthren-3-one (0.085 g, 75%) as yellow solid, which was used directly in the next step. TLC (eluting with 25% EtOAc in petroleum ether) Rf=0.4.
