실험 절차
A mixture of 5-bromo-2-chloro-4-(5-methyl-1H-pyrazol-3-ylamino)pyrimidine (Method 1; 290 mg, 11.0 mmol), 2-(2-aminoethyl)furan (330 mg, 3.0 mmol) and 1-butanol (5 ml) was heated at 120° C. for 5 hours. The mixture was allowed to cool to ambient temperature and the volatiles removed by evaporation. The residue was dissolved in DCM and washed with water followed by brine. The organics were separated, dried (MgSO4) and the solvent removed by evaporation. The residue was triturated with ether, the solid product collected and purified by column chromatography on silica gel eluting with DCM/methanol (95:5) to give the titled compound (80 mg, 22%). 1H NMR (DMSO): δ 2.1 (s, 3H), 2.85 (m, 2H), 3.45 (m 2H), 6.10 (m, 1H), 6.35 (m, 1H), 6.4 (br s, 1H), 7.15 (br s, 1H), 7.5 (s, 1H), 8.0 (br s, 2H), 12.05 (br s, 1H); MS: m/z 363.
