Reaction Conditions

Reaction Steps

A mixture of 5-(cyclopropylmethoxy)pyridin-2-amine (328 mg), 2-bromo-1-(4-hydroxyphenyl)ethanone (430 mg) and ethanol (10 mL) was stirred at 80° C. for 4 hr. The reaction mixture was allowed to cool to room temperature, and the resulting crystals were collected by filtration. The obtained crystals were dissolved in saturated aqueous sodium hydrogen carbonate solution and THF, and the solution was extracted twice with ethyl acetate. The combined organic layer was washed with saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure to give the title compound as a brown solid (561 mg).
