실험 절차

To a solution of 6-chloro-8-(2-chlorophenyl)-9-(4-chlorophenyl)-9H-purine (309 mg, 0.824 mmol, 1 eq.) in 10 mL of ethanol was added tert-butyl N-(piperidin-4-yl)carbamate (329 mg, 1.65 mmol, 2 eq.). The reaction was heated to 80° C. 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 442 mg (99%) of tert-butyl N-{1-[8-(2-chlorophenyl)-9-(4-chlorophenyl)-9H-purin-6-yl]piperidin-4-yl}carbamate. 1H NMR (300 MHz, CHLOROFORM-d) δ ppm 1.40-1.53 (m, 11 H) 2.12 (d, J=11.40 Hz, 2 H) 3.32 (t, J=11.63 Hz, 2 H) 3.80 (br. s., 1 H) 4.41-4.68 (m, 1 H) 5.40 (br. s., 2 H) 7.16-7.24 (m, 2 H) 7.26-7.43 (m, 5 H) 7.51 (d, J=6.59 Hz, 1 H) 8.38 (s, 1 H), [M+H]+ 539.2.
