2-[4-(4-Acetylpiperazin-1-yl)anilino]-4-(1-isopropyl-2-methyl-1H-imidazol-5-yl)-5-chloropyrimidine → 2-[4-(piperazin-1-yl)anilino]-4-(1-isopropyl-2-methyl-1H-imidazol-5-yl)-5-chloropyrimidine

Participants

Reaction Steps

The title compound was prepared from 2-[4-(4-acetylpiperazin-1-yl)anilino]-4-(1-isopropyl-2-methyl-1H-imidazol-5-yl)-5-chloropyrimidine (Example 33; 800 mg) by the method of Example 20. Except that after purification by chromatography on neutral alumina, activity II eluting with MeOH:DCM (3:97) the title compound was isolated as a yellow gum. Trituration with ether gave a foam (50 mg 7%). NMR: 1.34 (d, 6H), 2.45 (s, 3H), 2.82 (m, 4H), 2.96 (m, 4H), 4.82 (septuplet, 1H), 6.85 (d, 2H), 7.41 (s, 1H), 7.42 (d, 2H), 8.49 (s, 1H), 9.43 (s, 1H); m/z 412.
