4-(6-Phenyl-3-vinylimidazo[1,2-a]pyrimidin-7-yl)benzaldehyde → 4-(3-Ethyl-6-phenylimidazo[1,2-a]pyrimidin-7-yl)benzaldehyde

Participants

Reaction Steps

100 mg 4-(6-phenyl-3-vinylimidazo[1,2-a]pyrimidin-7-yl)benzaldehyde (prepared as described under example 15 are dissolved in a mixture of 5 ml THF and 5 ml EtOH. 10 mg 10% Pd/C are added and the mixture stirred under an atmosphere of hydrogen for 2 h. The mixture is filtered of celite, the solvens is evaporated and the crude product is purified by chromatography on silica gel (dichloromethane/methanol).
