Reaction Steps

A suspension of 2-(4-hydroxy-2,6-dimethylphenyl)-4-(tetrahydropyran-4-ylmethyl)cyclopentane-1,3-dione (0.104 g, 0.00033 mol), 2,6-dichloroquinoline (0.065 g, 0.00033 mol) and potassium carbonate (0.140 g, 0.00101 mol) in anhydrous N,N-dimethylformamide (3 ml) is heated at 140° C. for 40 minutes under microwave irradiation. After cooling to room temperature the reaction mixture was quenched with 2M hydrochloric acid and extracted with ethyl acetate. The organic phase is separated, washed with distilled water then dried over anhydrous magnesium sulfate. The mixture is filtered, the filtrate is evaporated in vacuo and the residue is purified by preparative reverse phase HPLC to afford 2-[4-(6-chloroquinolin-2-yloxy)-2,6-dimethylphenyl]-4-(tetrahydropyran-4-ylmethyl)cyclopentane-1,3-dione.
