反应详情

A mixture of 3.0 g of 1-aminoisoquinoline, 6.7 g of 2'-methyl-2-bromoacetophenone and 17.5 g of sodium bicarbonate in 50 ml of ethanol was refluxed for 2 hours. After being cooled, the reaction mixture was poured into water and extracted with ethyl acetate. The extract was washed with water and saturated saline, and dried over anhydrous magnesium sulfate. The drying agent was removed by filtration, and the solvent was removed under reduced pressure. The residue was purified by column chromatography on silica gel and recrystallized from dichloromethane/petroleum ether to give 4.4 g of the title compound as pale brown prisms.
