실험 절차
A suspension of 8-bromo-9-butyl-9H-purin-6-ylamine (0.50 g, 1.85 mmol) and thiourea (1.49 g, 19.6 mmol) in n-butanol (10 ml) was heated to reflux for 14 h. Dilution with CH2Cl2 (70 ml), washing with water and concentration afforded 6-amino-9-butyl-7,9-dihydro-purine-8-thione as a white powder (0.42 g, 1.87 mmol, 100%). 1H NMR (DMSO-d6) δ 12.35-12.25 (br. s, 1H), 8.13 (s, 1H), 6.92-6.72 (br. s., 2H), 4.09 (t, J=7.6 Hz, 2H), 1.71 (quint., J=7.5 Hz, 2H), 1.29 (sext., J=7.5 Hz, 2H), 0.87 (t, J=7.4 Hz, 3H).
