Reaction Steps

To a DMF (25 mL) solution of 4,5-dihydro-6-(3-methyloxyhexyl)naphtho[1,2-d]thiazol-2-ylamine (7) (4.5 g), 3-(4-bromo-2,6-difluorophenyl)-2-methylacrylic acid ethyl ester (3) (4.35 g), and dichlorobistriphenylphosphinepalladium (0.8 g) was added triethylamine (10 mL), and the reaction mixture was stirred under carbon monoxide atomosphere at 85° C. for 16 h. To the reaction mixture was added water, and the reaction mixture was extracted with ethyl acetate. The organic layer was washed with water, and brine, dried over magnesium sulfate, and evaporated. The obtained residue was purified by column chromatography (hexane:ethyl acetate=4:1) to obtain the compoumd (8) 7.1 g.
