Participants

Reaction Steps

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 dichloromethane was added methanesulfonyl chloride (0.007 mL, 0.091 mmol, 2 eq.) and triethylamine (0.02 mL, 0.137 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 12 mg (51%) of 8-(2-chlorophenyl)-9-(4-chlorophenyl)-N-[(3R)-1-methanesulfonylpiperidin-3-yl]-9H-purin-6-amine. 1H NMR (300 MHz, CHLOROFORM-d) δ ppm 1.81-2.18 (m, 4 H) 2.77-2.94 (m, 3 H) 3.07-3.29 (m, 2 H) 3.42 (br. s., 1 H) 3.82 (d, J=9.89 Hz, 1 H) 4.68 (br. s., 1 H) 6.13 (br. s., 1 H) 7.12-7.65 (m, 8 H) 8.48 (s, 1 H), [M+H]+ 517.8.
