Potassium Carbonate → N-(4-((4-(4,6-dimethoxypyrimidin-2-yl)piperazin-1-yl)methyl)phenylmethyl)acetamide

Participants

Reaction Steps

A solution of N-(4-((piperazin-1-yl)methyl)phenylmethyl)acetamide (5.0 g) obtained in Example 88(2), 2-chloro-4,6-dimethoxypyrimidine (3.9 g) and potassium carbonate (4.2 g) in acetonitrile (50 ml) was refluxed under heating for 5 hr. The reaction mixture was poured into ice water and extracted with ethyl acetate. The extract was washed with brine and dried over anhydrous sodium sulfate. The solvent was evaporated to give a pale-brown solid. The obtained pale-brown solid was purified by silica gel column chromatography (developing solvent; chloroform:methanol=9:1) and crystallized from diisopropyl ether to give the title compound (5.0 g) as white crystals.
