Triethylamine → 8-(2-chlorophenyl)-9-(4-chlorophenyl)-N-(1-methanesulfonylpiperidin-4-yl)-9H-purin-6-amine

Participants

Reaction Steps

To a solution of 8-(2-chlorophenyl)-9-(4-chlorophenyl)-N-(piperidin-4-yl)-9H-purin-6-amine (18.4 mg, 0.042 mmol, 1 eq.) in 2 mL of THF was added methanesulfonyl chloride (0.005 mL, 0.063 mmol, 1.5 eq.) and triethylamine (0.02 mL, 0.126 mmol, 3 eq.). The mixture was 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 20 mg (91%) of 8-(2-chlorophenyl)-9-(4-chlorophenyl)-N-(1-methanesulfonylpiperidin-4-yl)-9H-purin-6-amine. 1H NMR (300 MHz, CHLOROFORM-d) δ ppm 1.58-1.76 (m, 2 H) 2.21 (d, J=10.64 Hz, 2 H) 2.76 (s, 3 H) 2.90 (t, J=10.93 Hz, 2 H) 3.77 (d, J=12.15 Hz, 2 H) 4.33 (br. s., 1 H) 5.84 (br. s., 1 H) 7.04-7.51 (m, 8 H) 8.36 (s, 1 H), [M−H]− 515.7.
