Participants

Reaction Steps

The title compounds were prepared from 8-(2,5-dimethoxy-phenylsulfanyl)-9H-purin-6-ylamine and 1-(2-bromo-ethyl)-2-chloro-benzene by a procedure similar to examples 1 and 2. The isomers were separated by preparative HPLC. 9-[2-(2-Chloro-phenyl)-ethyl]-8-(2,5-dimethoxy-phenylsulfanyl)-9H-purin-6-ylamine: Yield 18%, 1H NMR (DMSO-d6) δ 8.23 (s, 1H), 7.82 (bs, 2H), 7.36 (dd, J=8.0, 1.2 Hz, 1H), 7.24-7.15 (m, 2H), 7.03-6.99 (m, 2H), 6.85 (dd, J=9.2, 3.2 Hz, 1H), 6.47 (d, J=2.8 Hz, 1H), 4.46 (t, J=7.2 Hz, 2H), 3.73 (s, 3H), 3.61 (s, 3H), 3.16 (t, J=7.2 Hz, 2H); LC-MS [M+H]+ 442.1. 3-[2-(2-Chloro-phenyl)-ethyl]-8-(2,5-dimethoxy-phenylsulfanyl)-3H-purin-6-ylamine: Yield, 11%, 1H NMR (DMSO-d6) δ 8.34 (s, 1H), 8.16 (bs, 1H), 7.41 (m, 1H), 7.29-7.11 (m, 6H), 4.56 (t, J=6.8 Hz, 2H), 3.76 (s, 3H), 3.72 (s, 3H), 3.30 (t, J=6.8 Hz, 2H), LC-MS [M+H]+ 442.1.
