실험 절차

To a solution of 8-(2-chlorophenyl)-9-(4-chlorophenyl)-N-[(3S)-piperidin-3-yl]-9H-purin-6-amine (16 mg, 0.036 mmol, 1 eq.) in 2 mL of THF was added triethylamine (0.015 mL, 0.109 mmol, 3 eq.) and ethyl isocyanate (0.004 mL, 0.055 mmol, 1.5 eq). The reaction is stirred for 16 h. The reaction was concentrated in vacuo. The crude material was purified by silica gel column chromatography using 0-100% ethyl acetate/hexanes to yield 16 mg (86%) of (3S)-3-{[8-(2-chlorophenyl)-9-(4-chlorophenyl)-9H-purin-6-yl]amino}-N-ethylpiperidine-1-carboxamide. 1H NMR (300 MHz, CHLOROFORM-d) δ ppm 1.06-1.34 (m, 3 H) 1.53-1.95 (m, 4 H) 2.12-2.29 (m, 1 H) 3.07 (br. s., 2 H) 3.32 (br. s., 1 H) 3.72-4.41 (m, 3 H) 5.06 (br. s., 1 H) 6.02 (d, J=6.12 Hz, 1 H) 7.08-7.66 (m, 8 H) 8.45 (br. s., 1 H), [M+H]+ 510.3.
