실험 절차

To a solution of 6-chloro-8-(2-chlorophenyl)-9-(4-chlorophenyl)-9H-purine (50 mg, 0.133 mmol, 1 eq.) in 2 mL of ethanol was added tert-butyl N-(4-phenylpiperidin-4-yl)carbamate (44 mg, 0.16 mmol, 1.2 eq) and triethylamine (0.03 mL, 0.20 mmol, 1.5 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 69 mg (84%) of tert-butyl N-{1-[8-(2-chlorophenyl)-9-(4-chlorophenyl)-9H-purin-6-yl]-4-phenylpiperidin-4-yl}carbamate. 1H NMR (300 MHz, CHLOROFORM-d) δ ppm 1.31-1.49 (m, 9H) 2.09-2.28 (m, 2 H) 2.43 (br. s., 2 H) 3.62 (br. s., 2 H) 4.96 (s, 1 H) 5.30 (br. s., 2H) 7.03-7.61 (m, 13H) 8.40 (s, 1 H), [M+H]+ 615.4.
