실험 절차

2-Amino-4-chloro-6-hydroxypyrimidine monohydrate (5.0 g) was refluxed in ethanol (150 mL) with cyclopropylamine for 12 h. The mixture was evaporated in vacuo, codistilled with ethanol (3×50 mL), adsorbed from methanol on silica gel and applied on a column of silica gel (200 mL) in chloroform. Elution with chloroform-ethanol gradient afforded crystalline product which was filtered from ether and dried in vacuo to afford 2-amino-4-cyclopropylamino-6-hydroxypyrimidine, m.p.229° C. Yield, 3.0 g. For C7H10N4O (166.18) calculated 50.59% C, 6.07% H, 33.71% N; found 50.49% C, 6.25% H, 33.61% N. 1H NMR (DMSO): 9.73 brs, 1H (OH); 6.55 bs, 2H (NH); 6.08 brs, 2H (NH2); 4.66 s, 1H (H-5); 2.30 m, 1H and 0.62 m, 2H and 0.40, m, 2H (C—CH2, N—CH).
