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 (33 mg) and potassium carbonate (12 mg) in N,N-dimethylformamide (5 ml) are added, at room temperature, potassium iodide (5 mg) and 3-bromoprop-1-yne (11 mg). The reaction mixture is stirred at 80° C. for 9 h. Then the mixture is admixed with dilute hydrochloric acid and extracted with ethyl acetate. The combined organic phases are dried over sodium sulphate and concentrated. Purification by column chromatography gives 2-[3,5-bis(difluoromethyl)-1H-pyrazol-1-yl]-1-[4-(4-{5-[2-chloro-6-(prop-2-yn-1-yloxy)phenyl]-4,5-dihydro-1,2-oxazol-3-yl}-1,3-thiazol-2-yl)piperidin-1-yl]ethanone (19 mg).
