실험 절차

A solution of the product obtained in Example 3, VII (R=H, R1 =C2H5) (359 mg, 0.724 mmol) in dimethyl sulfoxide (10 ml) under N2 was treated with 1N NaOH (1.81 ml, 1.81 mmol), stirred in a stoppered flask under N2 for 6 hours, and evaporated to dryness in vacuo at <30° C. A solution of the residue in water (18 ml) was filtered and acidified to pH 3.6 with 1N HCl. The precipitate was collected by filtration, washed with water at pH 3.6 and dried in vacuo (P2O5); yield 297 mg (87%), mp indefinite (softens above 200° C.); mass spectrum, m/e 440 (M+1)+ ; λmax nm (εx 10-3): 0.1N HCl-218 (40.5), 280 sh (16.9), 300 (18.8); pH 7-218 (38.5), 245 (19.2), 280 (23.9), 296 sh (22.7); 0.1N NaOH-248 (22.0), 280 (24.4), 296 sh (22.7), 345 (7.75); 1H-NMR (DMSO-d6, 6% w/v), δ2.00 m (CH2CH2CO), 2.29 t (CH2CO), 4.36 m (CHN, CH2N), 6.66 d, 7.68 d (C6H4), 7.41 (NH2), 8.04 m (NH2, NH, CO2H), 8.52 d, 8.70 d (5-CH, 7-CH).
