실험 절차

Adapting a protocol by Catarzi et al (J. Med Chem., 2001, 44, 3157–3165), diformylhydrazine (352 mg, 4.0 mmol) and then dropwise trimethylsilyl chloride (2.53 mL, 20 mmol) and Et3N(1.30 mL, 9.3 mmol) were added to a suspension of 4-aminophenylacetic acid (201 mg, 1.33 mmol) in anhydrous pyridine. The mixture was heated at 100° C. overnight, volatiles were removed at reduced pressure and the resulting solid was treated with water (6 mL), collected, washed with H2O and dried in vacuo to provide 251 mg (93%) of 141JP01 as a light brown solid. LCMS m/z 204[M+H]+. 1H-NMR (DMSO-d6) δ 9.05 (s, 2H), 7.62 (d, 1H, J=8.6), 7.40 (d, 1H, J=8.2), 3.61 (s, 2H).
