Reaction Steps

A mixture of [3-(4-bromobenzyl)-4-difluoromethoxy-2-ethyl-8-fluoroquinolin-5-yloxy]acetic acid methyl ester (0.36 g), 2-tributylstannanyloxazole (0.46 mL), tetrakis(triphenylphosphine)palladium(0) (0.084 g) and 1,4-dioxane (3.0 mL) was heated at 100° C. for 3 hours. The mixture was cooled to room temperature, diluted with ethyl acetate, washed with water, and then dried over magnesium sulfate. The solvent was removed under reduced pressure to afford title compound as a yellow gum (1.1 g).
