実験手順

2-(4-Morpholinoanilino)-6-cyclohexylamino-purine (i.e., reversine or Compound A) was synthesized using the methods similar to those previously described in Ding et al., J. Am. Chem. Soc. 124:1594 (2002). To a solution of 2-fluoro-6-chloropurine (87 mg, 0.5 mmol) in n-butanol (5 mL) was added cyclohexylamine (58 μL, 0.5 mmol) and diisopropylethylamine (100 μL, 0.6 mmol). The mixture was heated to 80° C. with vigorous stirring for 12 hours. The solvent was then removed under reduced pressure and the crude was used directly in the next step reaction without further purification. The crude 2-fluoro-6-cyclohexylamino-purine (0.5 mmol) was dissolved in ethanol (1 mL), followed by addition of 4-morpholinoaniline (178 mg, 1.0 mmol). The mixture was heated to 75° C. in a sealed tube with vigorous stirring for 24 hours. The solvent was then removed under reduced pressure and the crude material was directly purified by flash chromatography to afford 2-(4-morpholinoanilino)-6-cyclohexylamino-purine as a pale white solid (130 mg, overall 67% yield). 1H NMR (500 MHz, DMSO-d6) δ 1.14-1.24 (m, 1H), 1.26-1.39 (m, 4H), 1.59-1.67 (m, 1H), 1.73-1.81 (m, 2H), 1.94-1.99 (m, 2H), 3.07 (dd, J=4.8, 4.7 Hz, 4H), 3.74 (dd, J=4.8, 4.7 Hz, 4H), 3.90-4.06 (m, 2H), 6.93 (d, J=9.1 Hz, 2H), 7.51 (d, J=8.8 Hz, 2H), 8.31 (s, 1H), 8.38 (br. s, 1H), 9.68 (br. s, 1H); 13C NMR (125 MHz, CD3OD) δ 26.1, 26.5, 33.4, 40.4, 52.1, 67.4, 116.5, 118.6, 124.9, 133.2, 141.8, 147.9, 148.6, 152.9, 153.3; MALDI-FTMS for C21H28N7O (MH+): calcd 394.2350. found 394.2341.
