Participants

Reaction Steps

To a solution of N-{[4-(aminomethyl)cyclohexyl]methyl}-8-(2-chlorophenyl)-9-(4-chlorophenyl)-9H-purin-6-amine (6 mg, 0.013 mmol, 1 eq.) in 5 mL of THF was added methanesulfonyl chloride (0.02 mL) and triethylamine (0.05 mL) The reaction was stirred at room temperature 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 5 mg (71%) of N-{[4-({[8-(2-chlorophenyl)-9-(4-chlorophenyl)-9H-purin-6-yl]amino}methyl)cyclohexyl]methyl}methanesulfonamide. 1H NMR (300 MHz, CHLOROFORM-d) δ ppm 0.82-1.16 (m, 2 H) 1.33-1.75 (m, 6 H) 1.77-2.02 (m, 2 H) 2.84-3.00 (m, 4 H) 3.00-3.16 (m, 1 μl) 3.43-3.80 (m, 2 H) 4.40-4.63 (m, 1 H) 5.89-6.18 (m, 1 H) 7.08-7.60 (m, 8 H) 8.44 (s, 1H), [M+H]+ 559.6.
