Reaction Steps

To a solution of 2-[3,5-bis(difluoromethyl)-1H-pyrazol-1-yl]-1-(4-{4-[5-(2-chloro-6-hydroxyphenyl)-4,5-dihydro-1,2-oxazol-3-yl]-1,3-thiazol-2-yl}piperidin-1-yl)ethanone (39 mg) and potassium carbonate (47 mg) in acetone (5 ml) is added, at room temperature, allyl bromide (33 mg). The reaction mixture is stirred at reflux for 5 h. Then the mixture is admixed with water and extracted with ethyl acetate. The combined organic phases are dried over sodium sulphate and concentrated. Purification by column chromatography gives 1-[4-(4-{5-[2-(allyloxy)-6-chlorophenyl]-4,5-dihydro-1,2-oxazol-3-yl}-1,3-thiazol-2-yl)piperidin-1-yl]-2-[3,5-bis(difluoromethyl)-1H-pyrazol-1-yl]ethanone (26 mg).
