実験手順
A solution of 4-chloroindolo[3,2-d]pyrimidinehydrochloride (240 mg, 1.0 mmol) [Monge, A.; Palop, J. A.; Goni, T.; Martinez-Crespo, F.; Recalde, I. J. Het. Chem., 1986, 23, 647-9.], and aniline (0.273 mL, 3 mmol) in ethanol (1 mL) is heated at reflux for 3 h, during which time the reaction becomes a thick suspension. After cooling to 25 C. and diluting with ethanol (4 ml) the mixture is filtered, and the crude product washed with water (15 mL), and ethanol (15 mL), giving 274 mg tan solid, which is recrystallized from DMF/water affording pure 4-anilinoindolo[3,2-d]pyrimidine hydrochloride (82 mg, 27%). 1H NMR (DMSO): δ12.79 (1H, brs), 11.04 (1H, brs), 8:94 (1H, s), 8.27 (1H, d, J=8.2 Hz), 7.96 (2H, d, J=7.5 Hz), 7.85 (1H, d, J=8.4 Hz), 7.71 (1H, t, J=7.7 Hz), 7.49 (2H, t, J=8.0 Hz), 7.41 (1H, t, J=7.6 Hz), 7.24 (1H, t, J=7.4 Hz).
