Versuchsvorschrift

To a solution of 8-(2-chlorophenyl)-9-(4-chlorophenyl)-N-[(3R)-piperidin-3-yl]-9H-purin-6-amine (20 mg, 0.046 mmol, 1 eq.) in 2 mL of THF was added triethylamine (0.02 mL, 0.137 mmol, 3 eq.) and ethyl isocyanate (0.005 mL, 0.068 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 15 mg (65%) of (3R)-3-{[8-(2-chlorophenyl)-9-(4-chlorophenyl)-9H-purin-6-yl]amino}-N-ethylpiperidine-1-carboxamide. 1H NMR (300 MHz, CHLOROFORM-d) δ ppm 1.03-1.34 (m, 3 H) 1.56-1.96 (m, 4 H) 2.18 (br. s., 1 H) 3.07 (br. s., 2 H) 3.32 (br. s., 1 H) 3.73-4.42 (m, 3 H) 5.05 (br. s., 1 H) 6.02 (d, J=5.84 Hz, 1 H) 7.09-7.63 (m, 8 H) 8.45 (br. s., 1 H), [M+H]+ 510.3.
