Reaction Steps
The tert-butyl N-(5-fluoro-4-methyl-2-pyridyl)carbamate (75.6 mg, 0.334 mmol) obtained in (F) was dissolved in tetrahydrofuran (2 ml) and added dropwise with n-butyl lithium (1.5 M solution in hexane, 0.468 ml, 0.702 mmol) at −78° C. under argon atmosphere. The reaction mixture was warmed to room temperature, stirred for 1 hour, cooled to −78° C. again, added dropwise with a solution of 2-(bromomethyl)-4-isopropyl-1,3-thiazole (84.6 mg, 0.384 mmol) in tetrahydrofuran (2 ml), and then warmed to room temperature. The reaction mixture was added with water and extracted twice with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was evaporated. The resulting residue was purified by silica gel column chromatography (chloroform:ethyl acetate=100:1) to obtain the title compound (40.0 mg, 33%).
